CHAPTER I WHAT IS query??? Research is barg alone the process of conclusion forces to a line after a organic pick up and psycho abbreviation of the situational concomitantors. Business suspense systematic and organized exploit to investigate a special(prenominal) line of work encountered in the work setting, that inescapably a solution. It comprises a series of steps objectiveed and executed, with the destination of conclusion attend tos to the issues that ar of occupation to the charabanc in the work environment.Business inquiry organized, systematic, observational critical, objective, scientific inquiry or investigating into a specific problem, under issuancen with the invention of finding states or solutions to it. Yeah, ga usah bingung sama yang nam any(pre nominative)a mahluk bernama PENELITIAN. Intinya penelitian itu kan nyelidikin suatu ma salah buat nemuin solusinya. Prosesnya ga jauh beda sama usaha kita nyari kebenaran suatu gossip atau cari haphazardness tentang orang yang kita gebet. Bedanya RISET BISNIS ini harus dikerjain secara sistematis, selective in digitationnya jelas, dan ada dalil-dalil keilmuan yang sudah diakui dan terbukti keabsahannya.Santai semua orang pasti bisa menaklukan binatang yang bernama PENELITIAN ini khususnya SKRIPSI (buat mahasiswa S1). Chayo Pasti bisa TYPE OF BUSINESS RESEARCH virtu anyy(prenominal) dissimilar purposes of look for to solve a trustworthy problem confront by the manager in the work setting, demanding a sequencely solution (applied inquiry). to generate a body of knowledge by essay to secure how plastered problems that evanesce in brasss back tooth be solved (basic enquiry). utilize query explore d one(a) with the intention of applying the results of the findings to solve specific problems currently macrocosm experienced in the organization.Basic/fundamental/pure inquiry inquiry do chiefly to enhance the draw ining of certain problems that comm tha t occur in organisational settings, and jutk methods of solving them. CHAPTER II THE HALLMARKS OF SCIENTIFIC RESEARCH The main distinguishing qualitys of scientific research 1. Purposiveness s gobted the research with a definite develop or purpose, purposive focus 2. Rigor cargonfulness, scrupulousness, the degree of crabby propositioneditude in research investigations. cracking theory-based base and a sound methodological design 3.Testableness research worker develops certain hypotheses, then these thunder mug be intumesce-tried by applying certain statistical probes to the info collected for the purpose 4. Replicability the results of the tests of hypotheses should be supported again and yet again when the equivalent type of research is repeated in other(a) similar circumtances 5. preciseness and confidence Precision the closeness of the findings to reality based on a assay. Reflects the degree of truth or axactitude of the results on the foot of the exempl ification to what really exist in the universe Confidence the probability that our estimations be correct 6.Objectivity the conclusions haggard by dint of the interpretation of the results of entropy analytic thinking based on the facts of the findings derived from actual data and not on our own subjective or emotional value 7. Generalizability the scope of applicability of the research findings in one organizational setting to other settings. The research sample design has to be logically real and a number of other details in the data- accrual methods aim to be meticulously followed 8. Parsimony simplicity in explaining the phenomena or problemsthat occur, and in generating solutions for the problems.Introduced with a good studying of the problem and the master(prenominal) calculates that deviates it good deviceual theoretic model The reason for following a scientific method is that the results impart be less prone to errors and more confidence can be displace in the findings because of the greater rigor in application of the design details. This as well as increases the replicability and generalizability of the findings. Makanya, ikutin deh aturan scientific method. Ibaratnya, meneliti juga ada rukunnya sama kayak sholat. Kalo kita sholat rukunnya berantakan, ga tertib urutan ga teratur, kan sholatnya jadi ga karuan tu.Ga jelas juntrungannya. Bisa-bisa ga ada artinya or ga ada nilainya. Prinsip harus bertindak sesuai rukun juga berlaku dalam melakukan penelitian. BUILDING BLOCKS OF scientific discipline IN RESEARCH logical implication the process by which we arrive at a reasoned conclusion by logical generalization of a cognise fact. Induction a process where we observe certain phenomena and on this basis arrive at conclusions. HYPOTHETICO-DEDUCTIVE METHOD 7 steps in the hypothetico-deductive method 1. Observation 2. preceding information gathering 3. Theory cooking 4. Hypothesizing 5.Further scientific data collection 6. Data outli ne 7. Deduction CHAPTER IV RESEARCH PROCESS Research process for basic and applied research 1. Observation broad domain of a manipulation of research refer identified 2. Preliminary data gathering interviewing, literature survey 3. Problem definition research problem delineated 4. Theoretical divinatory account inconstants clearly identified and labeled 5. Generation of hypotheses 6. Scientific research design 7. Data collection, abbreviation, and interpretation 8. Deduction hypotheses substantiated? Research question settlemented?Kalau pada tahap ini hipotesis dan pertanyaan permasalahan belum terjawab, maka kita harus kembali ke proses 2, 3, 4, 5, 6, atau pun 7. Yang sabar ya say( Kalau sudah terjawab, ya lanjut ke tahap selanjutnya 9. track writing 10. Report presentation 11. Managerial decision making Yeah, tahap pertama pasti observasi dulu. Gue inget banget, waktu pertama-tama dulu gue bilang mau ngangkat Kampung Betawi buat objek penelitian. Aswin bilang gini deh Kam u observasi dulu tu Kampung Betawi selama seminggu penuh berturut-turut. Kalo perlu, lo ga pulang-pulang, diem aja lo disana.Liatin orang-orang yang dateng, ada apa aja disana, ngapain aja, mereka dateng dari mana, pokoknya perhatiin apa aja yang terjadi di sana . Ga berenti sampe disitu Gue disuruh wawancara si empunya yang berkuasa di Kampung Betawi itu. Tanya tentang Kampung Betawi, secara implisit tanyain juga masalah apa yang dihadapi sama Kampung Betawi, gali sebanyak-banyaknya informasi untuk memahami objek penelitian lo. Dan yang ga kalah penting tanyain mereka punya data-data sesuai kebutuhan lo ga mereka bisa kasih data itu ke lo ga. Ini pentingKalo mereka ga bisa kasih data sesuai kebutuhan lo, batalkan niat lo buat ngangkat tu objek. Gue saranin (sangat) lo ganti objek aja. Daripada tar lo repot belakangan, mending antisipasi dari awal khan Oh, iya ga ketinggalan, gue juga disuruh cari teori dan penelitian terdahulu yang relevan. Untuk memudahkan gue di masa mendatang. K alo lo udah observasi dan preliminary data gathering, baru deh lo bisa menemukan masalah utama yang akan lo angkat, secara spesifik, apa permasalahan yang picket fence menarik, discolor kritis, paling menggelitik, paling sensasional, yang paling membuat lo bertanya-tanya geregetan and penasaranSilakan berkhayal Abis itu, dengan teori-teori yang lo temukan, lo bikin model deh Despite the fact that the research model is depicted and discussed in this book as if it were a step-by-step linear process, one has to bear in mind that it is not actually so in practice. For example, though the literature search and interviews king view been conducted before formulating the theoretical framework, one may contrive to go back and conduct more interviews and/or seek additional information from the literature for a cle arr understanding, so as to refine the theory. Gue setuju banget sama pernyataan iniSoalnya gue juga ngerasain harus balik lagi, balik lagi, balik lagi, sampe gue bener-bener ng edapetin apa yang gue mau. Interview, nemu teori, interview, nemu teori, cari ketersediaan data, AARGGHH Mo gila Mungkin ini yang dimaksud aswin kalo nanti ternyata penemuan kamu ga cocok, ya kita rombak lagi. Sadis Sialan. Tapi kita tetap harus sabar SEMANGAAAAATTT Gue jadi inget pertanyaan Hermas kapan kita tau kalo penelitian kita udah bener-bener BENER??? . Dan aswin menjawab dengan sok romantis itu semua tergantung kecintaan kalian terhadap ilmu pengetahuan(.Makanya, bikin penelitian tentang sesuatu yang benar-benar lo sukai, lo cintai. Jadi di tengah-tengah kegilaan dan kebingungan, masih ada alasan waras kenapa lo masih mau ngelanjutin tu penelitian karna gue suka banget (selain karna alasan harus ngerjain skripsi su earningsa bisa lulus dari FE). Percaya deh, mengerjakan sesuatu yang lo suka bakal bikin HIDUP lebih HIDUP. OBSERVATION 1. Problems currently existing in an organizational setting that need to be solved 2. Areas that a manager believes need to be correctd in the organization 3.A notionual or theoretical issue that needfully to be tightened up for the basic researcher to understand certain phenomena 4. Some research questions that a basic researcher wants to answer empirically PRELIMINARY DATA COLLECTION 1. Background information of the organization that is, the contextual factors The origin and history of the company when it came into being, business concern it is in, rate of growth, self-will and control, and so on Size in terms of employees, assets, or both Charter purposes and ideology Location regional, national, or other Resources human and others inter symbiotic familys with other institutions and the external environment Financial position during the antecedent 5 to 10 years, and relevant financial data 2. Managerial philosophy, company policies, and other structural aspects Roles and positions in the organization and number of employees at all(prenominal) barter direct Extent of specialization Communication chann els Control systems Coordination and thwart of control Reward systems Workflow systems and the like 3. Perceptions, attitudes, and behavioral rejoinders of organizational members and guest systems (as applic qualified) Nature of the work Workflow interdependencies Superiors in the organization Participation in decision making Client systems Co-workers Rewards provided by the organization, such as pay raises and fringe benefits Opportunities for advancement in the organization Organizations attitudes toward employees family responsibilities lodges involvement with community, civic, and other social convocations Companys border of employees taking era off from the job LITERATURE SURVEY Good literature survey ensure that 1. Important multivariates that ar likely to influence the problem situation argon not left out of the film 2.A cle arr idea emerges as to what uncertains would be intimately important to consider (parsimony), wherefore they would be consider ed important, and how they should be investigated to solve the problem. Thus, the literature survey helps the development of the theoretical framework and hypotheses for exam 3. The problem statement can be do with precision and clarity 4. Testability and replicability of the findings of the current research are enhanced 5. single(a) does not run the risk of reinventing the wheel that is, wasting efforts on trying to rediscover several(prenominal)(a)thing that is already known 6.The problem investigated is perceived by the scientific community as relevant and substantive PROBLEM DEFINITION constrict shovel in the problem from its original broad base and outline the issues of concern more clearly. It is critical that the focus of further research, or in other words, the problem, be unambiguously identified and defined. No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed. A problem do es not inescapably mean that something is seriously wrong with a current situation that needs to be rectified immediately. A problem could simply indicate an engross in an issue where finding the right answers might help to improve an existing situation. It is fruitful to define a problem as any situation where a gap exists mingled with the actual and the desired nonesuch states. Is this factor I take on identified an antecendent, the real problem, or the consequence? Problem definition or problem statement a clear, precise, and drumhead statement of the question or issue that is to be investigated with the goal of finding an answer or solution. Could pertain to 1. Existing business problems where a manager is looking for a solution (applied research) 2.Situations that may not pose any current problems but which the manager feels have scope for improvement (applied research) 3. Areas where some planual clarity is need for better theory building (basic research) 4. Situa tions in which a researcher is trying to answer a research question empirically because of care in the topic (basic research) CHAPTER V NEED FOR supposed FRAMEWORK Theoretical framework a conceptual model of how one theorizes or makes logical sense of the relationships among the several factors that have been identified as important to the problem. This theory flows logically from documentation of previous research in the problem heavens. ? Integrating ones logical beliefs with published research, taking into consideration the boundaries and constraints governing the situation, is pivotal in exploitation a scientific basis for investigating the research problem. ? Theoretical framework discusses the interrelationships among the uncertains that are deemed to be integral to the dynamics of the situation being investigated. From the theoretical framework, then, tes plug-in hypotheses can be developed to examine whether the theory formulated is valid or not. ? The full(a) research rests on the basis of the theoretical framework. VARIABLES Variable anything that can take on differing or varying values. 4 main types of variables 1. bodeent variable (also known as the criterion variable) 2. self-sufficing variable (also known as visitor variable) 3. Moderating variable 4. Intervening variable Dependent variable Variable of elemental interest to the researcher The researchers goal is to understand and limn the low-level variable, or to explain its variability, or predict it The main variable that lends itself for investigation as a viable factor It is possible to have more than one mutually beneficial variable in a field of battle Pantesan Mungkin ini yang dimaksud aswin dengan pertanyaan yang selalu dia tujukan ke gue WHAT DO YOU WANT???.. tujuan lo apa sih??? Lo mau apa ha??? . Nah, kalo kayak gini gue jadi bingung lagi nih. Jadi dependent variable gue jumlah pengunjung atraksi wisata budaya PBB atau keinginan mengunjungi atraksi wisata budaya PBB? ???? Duh jadi bingung mikir lagi deh.Wahai teman, makanya selalu tanyakan dan pastikan tujuan akhir apa yang lo mau??? . Itulah dependent variable lo (hmm,,, sepertinya ini ga cuma berlaku buat penelitian deh, tapi dalam kehidupan nyata lo juga what do you want??? ) Independent variable One that influences the dependent variable in either a positive or negative way When the main(a) variable is present, the dependent variable is also present With distributively unit of increase in the independent variable, there is an increase or decrease in the dependent variable also Variance in the dependent variable is accounted for by the independent variableModerating variable One that has a strong contingent prepare on the independent variable-dependent variable relationship Whenever the relationship betwixt the independent variable and dependent variable becomes contingent or dependent on another variable, we say that the third variable has a moderating gear up on the independent v ariable-dependent variable relationship The variable that moderates the relationship is known as the moderating variable Intervening variable One that surfaces betwixt the time the independent variables start operational to influence the dependent variable and the time their impact is felt on it There is thus a temporal quality or time dimension to the intervening variable The intervening variable surfaces as a function of the independent variable(s) operating in any situation, and helps to conceptualize and explain the influence of the independent variable(s) on the dependent variable THEORETICAL FRAMEWORK ? It becomes evident at this story that to arrive at good solutions to the roblem, one should correctly identify the problem first, and then the variables that contribute to it. ? After identifying the take away variables, the next step is to work out the ne 2rk of associations among the variables, so that relevant hypotheses can be developed and subsequently tested. ? Based on the results of hypotheses interrogatory (which would indicate whether or not the hypotheses have been supported), the end to which the problem can be solved would become evident.Theoretical framework elaborates the relationships among the variables, explains the theory underlying these relations, and describes the constitution and concern of the relationships. A good theoretical framework identifies and labels the important variables in the situation that are relevant to the problem identified. Berarti gue bener donggue ga ngikutin teori dan penelitian lainnya secara plek-plekan sama Gue pake mereka dengan menyesuaikan diri dengan kondisi kasus gue, si PBB. 5 basic features that should be incorporate in any theoretical framework 1.The variables considered relevant to the ruminate should be clearly identified and labeled in the discussions. 2. The discussions should state how ii or more variables are related to one another. This should be done for the important relatio nships that are theorized to exist among the variables. 3. If the nature and direction of the relationships can be theorized on the basis of findings of previous research, then there should be an indication in the discussions as to whether the relationships would be positive or negative. 4. There should be a clear explanation of why we would expect these relationships to exist.This arguments could be drawn from the previous research findings. 5. A schematic diagram of the theoretical framework should be given so that the reader can see and easily circumnavigate the theorized relationship. HYPOTHESES DEVELOPMENT Hypotheses development formulating such testable statement Hypotheses a logically conjectured relationship amidst two or more variables expressed in the form of a testable statement ? To call a relationship statistically noteworthy, we should be confident that 95 times out of 100 the observed relationship will hold true ? Only a 5% chance that the relationship would not b e detectedStatement of hypotheses format If-then statement directional ? The direction of the relationship in the midst of the variables (positive/negative) is indicated ? The nature of the release between two groups on a variable (more than/less than) is postulated Nondirectional ? Do postulate a relationship or difference, but twist no indication of the direction of these relationships or differences ? It may be conjectured that there would be a significant relationship between two variables, we may not be able to say whether the relationship would be positive or negative ? develop either because the relationships or differences have never been previously explored &038 no basis for indicating the direction, or because there have been conflicting findings in previous research studies on the variables unprofitable and switch over hypotheses Null hypothesis a hypnotism that states a definitive, exact relationship between two variables ? States that the world correlation c oefficient between two variables is equal to nought or that the difference in the representation of two groups in the population is equal to zero (or some definite number) ?Expressed as no (significant) relationship between two variables or no (significant) difference between two groups Alternate hypotheses the mated of the null ? Statement expressing a relationship between two variables or indicating differences between groups If we reject the null hypothesis, then all permissible alternating(a) hypotheses relating to the cross relationship tested could be supported Example directional (group differences) ? Null hypothesis H0 M = W H0 M W = 0 ? Alternate hypothesis HA M < W HA M > W Nondirectional (group differences) ? Null hypothesis H0 AM = AS H0 AM AS = 0 Alternate hypothesis H0 AM ? AS Directional (relationship between 2 variables) ? Null hypothesis H0 there is no relationship between stress experienced on the job and the job satisfaction of employees H 0 ? = 0 ? Alternate hypothesis HA ? < 0 Nondirectional (relationship between 2 variables) ? Null hypothesis H0 ? = 0 ? Alternate hypothesis HA ? ? 0 locomote in hypotheses testing 1. State the null and the riffle hypotheses 2. Choose the admit statistical test depending on whether the data collected are parametric or nonparametric 3. Determine the level of importee desired (p=0. 5, or more, or less) 4. See if the output results from computer psychoanalysis indicate that the significance level is met. If, as in the case of Pearson correlation analysis in Excel software, the significance level is not indicated in the printout, look up the critical values that defined the regions of acceptance on the appropriate table (t, F, X2) see tables at the end of the book. This critical value demarcates the region of rejection from that of acceptance of the null hypotheses. 5. When the resultant value is hulkingr than critical value, the null hypotheses is rejected, and the alternate accepted.If the calculated value is less than the critical value, the null is accepted and the alternate rejected. Hypotheses generation and testing can be done both through with(predicate) deduction and induction Deduction the theoretical model is first developed, testable hypotheses are then formulated, data collected, and then the hypotheses are tested. Induction new hypotheses are formulated based on what is known from the data already collected, which are then tested. CHAPTER VI RESEARCH DESIGN Purpose of the study Types of investigation Extent of researcher interference Study setting Unit of analysis (population to be studied) Time horizon PURPOSE OF THE contain Exploratory study When not lots is known to the highest degree the situation at hand, or no information is procurable on how similar problems or research issues have been solved in the past To better comprehend the nature of the problem since very few studies might have been conducted in that area When s ome facts are known, but more information is needed for developing a viable theoretical framework For obtaining a good graps of the phenomena of interest and advancing knowledge through subsequent theory building and hypotheses testingDescriptive study To ascertain and be able to describe the characteristics of the variables of interest in a situation The goal to offer to the researcher a profile or to describe relevant aspects of the phenomena of interest from an single(a), organization, industry-oriented, or other perspective invest data in meaningful form, help to ? Understand the characteristics of a group in a given situation ? Think systematically about aspects in a given situation ? Offer ideas for further canvass and research ? Help make certain simple decisions Hypotheses testing condone the nature of certain relationships, or defecate the differences among groups or the independence of two or more factors in a situation To explain the var. in the dependent vari able or to predict organizational outlet Case study analysis Involve in-depth, contextual analyses of matters relating to similar situations in other organizations Problem-solving technique Qualitative in nature, useful in applying solutions to current problems based on past problem-solving experiences Useful in understanding certain phenomena, and generating further theories for empirical testingTYPE OF INVESTIGATION Causal study the study in which the researcher wants to delineate the cause of one or more problems correlational study when the researcher is interested in delineating the important variables associated with the problem STUDY SETTING Field studies correlational studies done in organizations Field experiments studies conducted to establish cause-and-effect relationship utilize the akin natural environment in which employees ordinarily fuctionLab experiments experiments done to establish cause and effect relationship beyond the porta of the least doubt require the creation of an artificial, contrived environment in which all the extraneous factors are strictly controlled. Similar subjects are choosen cautiously to respond to certain manipulated stimuli UNIT OF ANALYSIS Unit of analysis level of aggregation of the data collected during the subsequent data analysis stage. Depend on problem statement focuses. Individual data gathered from individually(prenominal) individual and treating distributively employees response as an individual data sourceDyads interested in studying two-persons interactions, then several two-persons groups Groups even though we may gather relevant data from all individuals comprising, we would aggregate the individual data into group data so as to see the differences among some groups (missal jadi 6 group) Our research question mends the unit of analysis. TIME HORIZON cross-sectional/one-shot studies data are gathered just once, perhaps over a period of days or weeks or moths, in order to answer a research que stionLongitudinal studies data on the dependent variable are gathered at two or more points in time to answer the research question CHAPTER VIII OPERATIONAL DEFINITION Operationalizing the concepts lessening of abstract concept to render them measurable in a obvious way Operationalizing defining a concept to render it measurable, is done by looking at the behavioral dimensions, facets, or properties denoted by the concept Operationalizing the concept ? They would probably have some typical broad characteristics, which we call dimensions. ? Examining each of the dimension and breaking each further into its members ?These should somehow be discernible and quantitatively measurable What an operational definition is not Does not describe the correlates of the concept Does not consist of delineating the reasons, antecedents, consequences, or correlates of the concept If we either operationalize the concepts falsely or confuse them with other concepts, then we will not have valid b eaks. This heart that we will not have good data, and our research will not be scientific. Yeahkalo kita salah mengoperasionalisasikan suatu variabel, fatal akibatnya.Bisa-bisa kita salah bikin pertanyaan buat diukur nilainya. Jelek deh datanya. (kayaknya gue baru sadar deh kalo gue salah operasionalisasi. Hix. ) Tips agar tidak salah operasionalisasi variabel ? Bikin landasan teori yang bagus semua berawal dari landasan teori ? Selalu temukan definisi yang tepat dari sebuah konsep ataupun variabel. DEFINISI itu kunci yang penting Kalo kata Lovelock -si professor pemasaran jasa yang kita selalu punya kunci cinta- If you cant define something, you cant mensuration it, and what you cant measure you cant manage. Punya definisi yang tepat, pasti akan menuntun lo kepada operasionalisasi variabel yang tepat. Ini teori gue, hehe ((((( (berdasarkan pengalaman pribadi). Pantesan, aswin selalu bertanya pada gue ini definisinya apa? Itu definisinya apa? . Hmmmm. pantesaku baru mengerti seka rang. SCALES Scale a tool or mechanism by which individuals are distinguished as to how they differ from one another on the variables of interest to our study 4 basic types of musical scale leafs nominal, ordinal, interval, and ratio tokenish scale One that allows researcher to assign subjects to certain categories or groups ?Assigned code number ? These number serve as simple and convenient year labels with no intrinsic value, other than to assign respondents to one of two nonoverlapping or mutually exclusive categories ? Note that the categories are also collectively complete(a) ? The information is to calculate the percentage (or frequency) Ordinal scale not tho categorizes the variables in such a way as to denote differences among the mingled categories, it also rank-orders the categories in some meaningful way ?Helps the researcher to determine the percentage of respondents who consider interaction with others as most important, those who consider using a number of diff erent skills as most important, and so on time interval scale let us measure the distance between any two points on the scale ? Helps us to compute the means and the mensuration deviations of the responses on the variables ? Not only groups individuals according to certain categories and lights-out the order of these groups, it also measures the magnitude of the differences in the preferences among individuals ? The origin, or the offset point, could be any arbitrary number ?More powerful scale than the nominal and ordinal scale, and has for its measure of substitution tendency the arithmetic mean ? It measures of diffusion are the range, the standard deviation, and the variance Ratio scale not only measures the magnitude of the differences between points on the scale but also lights-out the proportions in the differences ? It has an absolute (in contrast to an arbitrary) zero point, which is a meaningful beat point ? The most powerful of the 4 scales because it has a unique zero origin (not an arbitrary origin) and subsumes all the properties of the other three scalesUse of 4 types of scales Nominal scale for obtaining personal data such as gender or department Ordinal scale to rank the preferences or usage of mingled brands of a product by individuals and to rank order individuals, objects, or events Interval scale when responses to various items that measure a variable can be tapped on a five-point (or seven-point or any other number of points) scale, which can thereafter be summated across the items Ratio scale when exact poem on objective (as opposed to subjective) factor are called for CHAPTER IXGOODNESS OF MEASURES Goodness of measures middling sure that the shafts we use in our research do indeed measure the variables they are supposed to, and that they measure them accurately Item analysis to see if the items in the instrument belong there or not. ? The means between the high-score group and the low-score group are tested to detect sig nificant difference through the t-values ? The items with a high t-value (test which is able to identify the super acuate items in the instrument) are then included in the instrumentRELIABILITY Reliability tests how consistently a measuring instrument measures whatever concept it is measuring tax stability and physical structure Reliability Stability of measures the ability of a measure to remain the same over time despite uncontrollable testing conditions or the state of the respondents themselves ? Test-retest dependableness the reliableness coefficient obtained with a repetition of the same measure on a second occasion, the higher(prenominal) the better ?Parallel-form reliability when responses on two comparable sets of measures tapping the same construct are highly check Internal consistency of measures the items should hang in concert as a set and be capable of independently measuring the same concept so that the respondents attach the same overall meaning to each of the items ? Interitem consistency reliability test of the consistency of respondents answer to all the items in a measure. To the degree that the items are independent measures of the same concept, they will be correlative with one another.Cronbachs coefficient alpha used for multipoint-scaled items, Kuder-Richardson formulas used for dichotomous items. The higher the coefficients, the better the measuring instrument ? Split-half reliability reflects the correlations between two halves of an instrument VALIDITY Validity tests how well an instrument that is developed measures the particular concept it is intended to measure Whether we measure the right concept Validity capacity validity ensures that the measure includes an adequate and congresswoman set of items that tap the concept.A function of how well the dimensions and elements of a concept have been delineated Criterion-related validity establish when the measure differentiates individuals on a criterion it is expected to predict pee validity testifies to how well the results obtained from the use of the measure fit the theories around which the test is designed ? Correlational analysis as in the case of establishing synchronous and predictive validity or convergent and discriminant validity ?Factor analysis a multivariate technique that would confirm the dimensions of the concept that have been operationally defined, as well as indicate which of the items are most appropriate for each dimension ? Multitrait multimethod hyaloplasm of correlations derived from measuring concepts by different forms and different methods CHAPTER XI POPULATION, ELEMENT, POPULATION FRAME, try on, &038 SUBJECT world the entire group of people, events, or things of interest that the researcher wishes to investigateElement a single member of the population Population frame a listing of all the elements in the population from which the sample is drawn take a subset of the population, it comprises some members selected from it Subject a single member of the sample SAMPLING Sampling the process of selecting a fitting number of elements from the population, so that the study of the sample and an understanding of its properties or characteristics would make it possible for us to generalize such properties or characteristics to the population elements ? each conclusions drawn about the sample under study are reason to the population ? Xbar, S, S2 are used as estimates of the population parameters ? , ? , ? 2 rationalness for try out Self-evident Time, cost, and other human resources considered Sometimes likely to beget more reliable results Representativeness of samples Rarely will the sample be the exact replica of the population from which it is drawn If we choose the sample in a scientific way, we can be reasonably sure that the sample statistic (e. . ,Xbar, S, S2) is pretty close to the population parameter (i. e. ,? , ? , ? 2) NORMALITY OF DISTRIBUTIONS ? Attributes or characteristic s of the population are generally normally distributed ? If we take a sufficiently large number of samples and choose them with care, we will have a take distribution of the means that has normality ? This is the reason that the two important issues in sampling are the sample size (n) and the sampling design ?If our sampling design and sample size are right, the sample mean Xbar will be in spite of appearance close range of the true population mean (? ) ? The more representative of the population the sample is, the more generalizable are the findings of the research 2 study types of sampling design 1. Probability sampling Simple random sampling Complex probability sampling ? Systematic sampling ? Stratified random sampling ? per capita and dissymmetrical stratified random sampling ? clunk sampling ? Single-stage and multistage cluster sampling Area sampling ? Double sampling 2. Nonprobability sampling Convenience sampling Purposive sampling ? Judgment sampling ? Quota sampling PROBABILITY SAMPLING Probability sampling when elements in the population have a known chance of being chosen as subjects in the sample Simple random sampling every element in the population has a known and equal chance of being selected as a subject ? outdo when the generalizability of the findings to the whole population is the main objective of the study Complex probability sampling Systematic sampling drawing every nth element in the population starting with a randomly chosen element between 1 and n ? trounce when the population frame is large, and a listing of the elements is conveniently available at one place Stratified random sampling a process stratification or segregation, followed by random selection of subjects from each stratum. The population is first divided into mutually exclusive groups that are relevant, appropriate, and meaningful in the context of the study ? trump out when differentiated information is needed regarding various strata inwardly the po pulation, which are known to differ in their parameters Proportionate and disproportionate stratified random sampling Proportionate the subjects drawn from each stratum, members represented in the sample from each stratum will be proportionate to the total number of elements in the respective strata Disproportionate the subjects drawn from each stratum, the number of subjects from each stratum will now be altered, while keeping the sample size unchanged Cluster sampling when several groups with intragroup heterogeneity and intergroup homogeneity are found, then a random sampling of the clusters or groups can ideally be done and information gathered from each of the members in the randomly chosen clusters ? Best when heterogeneous group is to be studied at one time Single-stage and multistage cluster sampling the division of of the population into convenient clusters, randomly choosing the required number of clusters as sample subjects, and investigating all the elements in each of the randomly chosen clusters Area sampling constitutes geographical clusters, when the research pertains to populations within identifiable geographical areas such as coutries, city blocks, or particular boundaries within a locality ? Best when the goal of the research is wrapped to a particular locality or area Double sampling where initially a sample is used in a study to collect some preliminary information of interest, and later a subsample of this primary sample is used to examine the matter in more detail ? Best provided added information at minimal additional expenditureNONPROBABILITY SAMPLING Nonprobability sampling the elements in the population do not have any probabilities tie to their being chosen as sample subjects Convenience sampling collection of information from members of the population who are conveniently available to provide it ? Best to obtain some quick information to get a feel for the phenomenon or variables of interest Purposive sampling confined a s pecific types of people who can provide the desired information, either because they are the only ones who have it, or conform to some criteria set by the researcher Judgment sampling the choice of subjects who are most advantageously placed or in the best position to provide the information required ? Best where the collection of specialized informed inputs on the topic area researched is vital, and the use of any other sampling design would not offer opportunities to obtain the specialized information Quota sampling a form of proportionate stratified sampling, in which a predetermined proportion of people are sampled from different groups, but on a convenience basis ?Best for the inclusion of all groups in the system researched ISSUES IN DETERMINING SAMPLE SIZE 1. Precision ? How close our estimate is to the true population characteristic ? The narrower this interval, the greater the precision ? A function of the range of variability in the sampling distribution of the sample mea n ? If we want to reduce the standard error given a particular standard deviation in the sample, we need to increase the sample size 2. Confidence ? How certain we are that our estimates will really hold true for the population ?Reflects the level of conclusion with which we can state that our estimates of the population parameters will hold true ? A 95% confidence is the conventionally accepted level for most business research, most commonly expressed by denoting the significance level as p? 0. 05 ? At least 95 times out of 100, our estimate will reflect the true population characteristic The sample size, n, is a function of 1. The variability in the population 2. Precision or true statement needed 3. Confidence level desired 4. Type of sampling plan used 4 aspects while making decisions on the sample size . How much precision is really needed in estimating the population characteristics of interest what is the margin of allowable errors? 2. How much confidence is really needed how much chance can we take of making errors in estimating the population parameters? 3. To what extent is there variability in the population on the characteristics investigated? 4. What is the cost-benefit analysis of change magnitude the sample size? Roscoe (1975) rules of thumb for determining sample size 1. Sample sizes larger than 30 and less than 500 are appropriate for most research 2.Where samples are to be broken into subsamples (exmale/female, etc), a borderline sample size of 30 for each category is necessary 3. In multivariate research (including multiple regression analysis), the sample size should be several times (preferably 10 times or more) as large as the number of variables in the study 4. For simple experimental research with tight experimental controls (matched pairs, etc), successful research is possible with samples as flyspeck as 10 to 20 in size Kalo menurut gue sih, tahapan yang paling genting dan paling kritis ya di pembuatan BAB 3 alias pembuatan/pen entuan metodologi ini.Ibaratnya bikin racikan obat, BAB 3 ini kayak tahap ketika lo lagi menentukan takaran dosis setiap elemen ramuan (ya populasi, ya sample, ya lainnya). Kalo dosisnya kurang, pasien ga sembuh, merana harus menderita terus-menerus. Kalo dosisnya berlebihan, pasien over dosis, meledak nanti Dua-duanya sama-sama gawat. Kalo lo udah bikin BAB 3 lo dengan benar, selanjutnya gampang kok, tinggal ngambil data or sebar kuesioner, analisa. Tingal jalan. ga perlu berlari-lari jatuh bangun kedebak-kedebuk. Well, udah bisa berpikir lebih santai lah.. Tapi ingetBAB 3 juga berasal dari BAB 2 computer simulation penelitian lo kan berasal dari landasan teori di BAB 2. salaah teori, bisa-bisa salah model. Salah model, berakibat salah operasionalisasi variabel. Salah operasionalisasi variabel, salah kuesioner. Salah kuesioner, salah data. Salah data, tebak sendiri. Tapi, BAB 2 juga berasal dari BAB 1 lho. Lo kan harus tau permasalahan lo dengan jelas tuh. Apa yang jadi latar bel akang permasalahannya, apa hasil akhir yang lo mau. Semua itu yang menentukan teori-teori apa aja yang lo butuhin untuk dicantumin Hahahaha.Intinya sih, semua harus dikerjakan secara berurutan yah BAB 1-2-3. Inget prinsip rukun yang gue jabarin di atas. Pokoknya selamat mengerjakan BAB1,2,3 bolak-balik deh. 1,2,3 3,2,1 2,1,3 begitu aja terus Yang penting sabar semua harus dikerjakan dengan ketenangan akal dan pikiran. Nikmatin aja prosesnya((( goodluck yo CHAPTER XII 4 steps in data analyis 1. Getting data ready for analyis 2. Getting a feel for the data 3. examen the goodness of data 4. Testing the hypotheses get DATA READY FOR ANALYSIS Editing data ? Data have to be edited Information that may have been noted down by the interviewer, observer, or researcher in a hurry must be clearly deciphered so that it may be coded systematically in its entirety ? Incoming mailed questionnaire data have to be checked for incompleteness and inconsistencies Handling outer space responses ? Not all respondents answer every item in the questionnaire ? Blank because the respondent did not understand the question, did not know the answer, was not willing to answer, or was simply impertinent to the need to respond to the entire questionnaire ?Way to handle a blank response Assign the midpoint in the scale as the response to that particular item Allow the computer to ignore the blank responses when the analysis are done Assign to the item the mean value of the responses of all those who have responded to that particular item Give the item the mean of the responses of this particular respondent to all other questions measuring this variable Give the missing response a random number within the range for that scale Coding ? Code the responses Coding sheet first to transcribe the data from the questionnaire and then key in the data Categorization ? Set up scheme for categorizing the variables such that the several items measuring a concept are all grouped together ? Resp onses to some of the negatively worded questions have also to be reversed so that all answers are in the same direction Entering data ? Questionnaire data are collected on scanner answer sheets or tha raw data manually name into the computer DATA ANALYSIS 3 objectives in data analysis 1.Getting a feel for the data 2. Testing the goodness of data 3. Testing the hypotheses developed for the research Feel for the data Examination of the measure of central tendency, and how clustered or dispersed the variables are, gives a good idea of how well the questions were framed for tapping the concept The statistics give feel for the data ? The frequency distributions for the demographic variables ? The mean, standard deviation, range, and variance on the other dependent and independent variables ?An intercorrelation matrix of the variables, irrespective of whether or not the hypotheses are directly related to these analysis Testing goodness of data Reliability ? Testing consistency and sta bility ? Consistency indicates how well the items measuring a concept hang together as a set ? Cronbachs alpha is a reliability coefficient that indicates how well the items in a set are positively correlated to one another ? The closer Cronbachs alpha is to 1, the higher the congenital consistency reliability Validity Factorial validity can be established by submitting the data for factor analysis ? The results of factor analysis (a multivariate technique) will confirm whether or not the theorized dimensions emerge Hypotheses testing Test the hypotheses already developed for the study Analisis.
