Vessey, I., Ramesh, V., & Glass, R. L. (2002). European Journal of Information Systems, 17(5), 627-645. The Earth is Round (p< .05). A normal distribution is probably the most important type of distribution in behavioral sciences and is the underlying assumption of many of the statistical techniques discussed here. The experimental hypothesis was that the work group with better lighting would be more productive. On the other hand, Size of Firm is more easily interpretable, and this construct frequently appears, as noted elsewhere in this treatise. Data Collection Methods and Measurement Error: An Overview. In multidimensional scaling, the objective is to transform consumer judgments of similarity or preference (e.g., preference for stores or brands) into distances in a multidimensional space. Other techniques include OLS fixed effects and random effects models (Mertens et al., 2017). When performed correctly, an analysis allows researchers to make predictions and generalizations to larger, more universal populations outside the test sample.1 This is particularly useful in social science research. Gefen, D., Straub, D. W., & Boudreau, M.-C. (2000). Statistical Significance Versus Practical Importance in Information Systems Research. Theory and Reality: An Introduction to the Philosophy of Science. Development of an Instrument to Measure the Perceptions of Adopting an Information Technology Innovation. the estimated effect size, whereas invalid measurement means youre not measuring what you wanted to measure. Typically, QtPR starts with developing a theory that offers a hopefully insightful and novel conceptualization of some important real-world phenomena. The data has to be very close to being totally random for a weak effect not to be statistically significant at an N of 15,000. Accordingly, a scientific theory is, at most, extensively corroborated, which can render it socially acceptable until proven otherwise. It may, however, influence it, because different techniques for data collection or analysis are more or less well suited to allow or examine variable control; and likewise different techniques for data collection are often associated with different sampling approaches (e.g., non-random versus random). A researcher expects that the time it takes a web page to load (download delay in seconds) will adversely affect ones patience in remaining at the website. For any quantitative researcher, a good knowledge of these tools is essential. This is because measurement provides the fundamental connection between empirical observation and the theoretical and mathematical expression of quantitative relationships. MIS Quarterly, 35(2), 293-334. With the advent of experimentalism especially in the 19th century and the discovery of many natural, physical elements (like hydrogen and oxygen) and natural properties like the speed of light, scientists came to believe that all natural laws could be explained deterministically, that is, at the 100% explained variance level. Bagozzi, R.P. Lauren Slater provides some wonderful examples in her book about experiments in psychology (Slater, 2005). It does not imply that certain types of data (e.g., numerical data) is reserved for only one of the traditions. All types of observations one can make as part of an empirical study inevitably carry subjective bias because we can only observe phenomena in the context of our own history, knowledge, presuppositions, and interpretations at that time. If your prediction is confirmed, verify your results, draw your final conclusions and present your findings. The ultimate goal for a company is to be able to utilize communication technology productively. Quantitative research is a systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical, or computational techniques. What is the value of quantitative research in people's everyday lives? This reasoning hinges on power among other things. Meta-analyses are extremely useful to scholars in well-established research streams because they can highlight what is fairly well known in a stream, what appears not to be well supported, and what needs to be further explored. A survey is a means of gathering information about the characteristics, actions, perceptions, attitudes, or opinions of a large group of units of observations (such as individuals, groups or organizations), referred to as a population. ), Criticism and the Growth of Knowledge (pp. B., Stern, H., Dunson, D. B., Vehtari, A., & Rubin, D. B. Kluwer Academic Publishers. Eventually, businesses are prone to several uncertainties. However, the analyses are typically different: QlPR might also use statistical techniques to analyze the data collected, but these would typically be descriptive statistics, t-tests of differences, or bivariate correlations, for example. Validation Guidelines for IS Positivist Research. If items load appropriately high (viz., above 0.7), we assume that they reflect the theoretical constructs. Management Science, 29(5), 530-545. (2020). accurate as of the publish date. Siponen, M. T., & Klaavuniemi, T. (2020). Sometimes there is no alternative to secondary sources, for example, census reports and industry statistics. Because a low p-value only indicates a misfit of the null hypothesis to the data, it cannot be taken as evidence in favor of a specific alternative hypothesis more than any other possible alternatives such as measurement error and selection bias (Gelman, 2013). Introductions to their ideas and those of relevant others are provided by philosophy of science textbooks (e.g., Chalmers, 1999; Godfrey-Smith, 2003). Historically, internal validity was established through the use of statistical control variables. Henseler, J., Dijkstra, T. K., Sarstedt, M., Ringle, C. M., Diamantopoulos, A., Straub, D. W., Ketchen, D. J., Hair, J. F., Hult, G. T. M., & Calantone, R. J. Heisenberg, W. (1927). As a conceptual labeling, this is superior in that one can readily conceive of a relatively quiet marketplace where risks were, on the whole, low. Communications of the Association for Information Systems, 8(9), 141-156. For example, experimental studies are based on the assumption that the sample was created through random sampling and is reasonably large. 221-238). Intermediaries may have decided on their own not to pull all the data the researcher requested, but only a subset. I did this, then I did that. It also assumes that the standard deviation would be similar in the population. Petter, S., Straub, D. W., & Rai, A. Where quantitative research falls short is in explaining the 'why'. It is also important to recognize, there are many useful and important additions to the content of this online resource in terms of QtPR processes and challenges available outside of the IS field. Low power thus means that a statistical test only has a small chance of detecting a true effect or that the results are likely to be distorted by random and systematic error. What are theories? (2009). Communication - How ICT has changed the way the researcher communicate with other parties. MIS Quarterly, 35(2), 261-292. (2014). You are hopeful that your model is accurate and that the statistical conclusions will show that the relationships you posit are true and important. Typically, researchers use statistical, correlational logic, that is, they attempt to establish empirically that items that are meant to measure the same constructs have similar scores (convergent validity) whilst also being dissimilar to scores of measures that are meant to measure other constructs (discriminant validity) This is usually done by comparing item correlations and looking for high correlations between items of one construct and low correlations between those items and items associated with other constructs. One problem with Cronbach alpha is that it assumes equal factor loadings, aka essential tau-equivalence. Alpha levels in medicine are generally lower (and the beta level set higher) since the implications of Type I or Type II errors can be severe given that we are talking about human health. Wilks Lambda: One of the four principal statistics for testing the null hypothesis in MANOVA. Inferential analysis refers to the statistical testing of hypotheses about populations based on a sample typically the suspected cause and effect relationships to ascertain whether the theory receives support from the data within certain degrees of confidence, typically described through significance levels. P Values and Statistical Practice. What matters here is that qualitative research can be positivist (e.g., Yin, 2009; Clark, 1972; Glaser & Strauss, 1967) or interpretive (e.g., Walsham, 1995; Elden & Chisholm, 1993; Gasson, 2004). Likewise, with the beta: Clinical trials require fairly large numbers of subjects and so the effect of large samples makes it highly unlikely that what we infer from the sample will not readily generalize to the population. Often, such tests can be performed through structural equation modelling or moderated mediation models. John Wiley & Sons. Cronbach, L. J. Also reminded me that while I am not using any of it anymore, I did also study the class, Quantitative Research in Information Systems, What is Quantitative, Positivist Research, http://www.janrecker.com/quantitative-research-in-information-systems/, https://guides.lib.byu.edu/c.php?g=216417&p=1686139, https://en.wikibooks.org/wiki/Handbook_of_Management_Scales. 3. If they include measures that do not represent the construct well, measurement error results. Or, the questionnaire could have been used in an entirely different method, such as a field study of users of some digital platform. This kind of research is commonly used in science fields such as sociology, psychology, chemistry and physics. Importantly, they can also serve to change directions in a field. MIS Quarterly, 30(2), iii-ix. This resource is structured into eight sections. As the original online resource hosted at Georgia State University is no longer available, this online resource republishes the original material plus updates and additions to make what is hoped to be valuable information accessible to IS scholars. Studying something so connected to emotions may seem a challenging task, but don't worry: there is a lot of perfectly credible data you can use in your research paper if only you choose the right topic. In this situation you have an internal validity problem that is really not simply a matter of testing the strength of either the confound or the theoretical independent variable on the outcome variable, but it is a matter of whether you can trust the measurement of either the independent, the confounding, or the outcome variable. There is a vast literature discussing this question and we will not embark on any kind of exegesis on this topic. Research in Information Systems: An Empirical Study of Diversity in the Discipline and Its Journals. An example situation could be a structural equation model that supports the existence of some speculated hypotheses but also shows poor fit to the data. Statistical Conclusion Validity: Some Common Threats and Simple Remedies. Surveys then allow obtaining correlations between observations that are assessed to evaluate whether the correlations fit with the expected cause and effect linkages. There are numerous excellent works on this topic, including the book by Hedges and Olkin (1985), which still stands as a good starter text, especially for theoretical development. Tabachnick, B. G., & Fidell, L. S. (2001). A researcher that gathers a large enough sample can reject basically any point-null hypothesis because the confidence interval around the null effect often becomes very small with a very large sample (Lin et al., 2013; Guo et al., 2014). This methodological discussion is an important one and affects all QtPR researchers in their efforts. (2013). Univariate analysis of variance (ANOVA) is a statistical technique to determine, on the basisof one dependent measure, whether samples come from populations with equal means. Emerging Varieties of Action Research: Introduction to the Special Issue. Davidson, R., & MacKinnon, J. G. (1993). The primary strength of experimental research over other research approaches is the emphasis on internal validity due to the availability of means to isolate, control and examine specific variables (the cause) and the consequence they cause in other variables (the effect). For example, the Inter-Nomological Network (INN, https://inn.theorizeit.org/), developed by the Human Behavior Project at the Leeds School of Business, is a tool designed to help scholars to search the available literature for constructs and measurement variables (Larsen & Bong, 2016). Thinking About Measures and Measurement in Positivist Research: A Proposal for Refocusing on Fundamentals. Emory, W. C. (1980). The researcher controls or manipulates an independent variable to measure its effect on one or more dependent variables. Statistical control variables are added to models to demonstrate that there is little-to-no explained variance associated with the designated statistical controls. Quantitative research is focused specifically on numerical information. Branch, M. (2014). Statistical Methods for Meta-Analysis. Morgan, S. L., & Winship, C. (2014). You can scroll down or else simply click above on the shortcuts to the sections that you wish to explore next. Of special note is the case of field experiments. In scientific, quantitative research, we have several ways to assess interrater reliability. For example, several historically accepted ways to validate measurements (such as approaches based on average variance extracted, composite reliability, or goodness of fit indices) have later been criticized and eventually displaced by alternative approaches. When we compare two means(or in other tests standard deviations or ratios etc. McNutt, M. (2016). This worldview is generally called positivism. It is out of tradition and reverence to Mr. Pearson that it remains so. This is . Falsification and the Methodology of Scientific Research Programs. Collect and process your data using one or more of the methods below. In addition to situations where the above advantages apply, quantitative research is helpful when you collect data from a large group of diverse respondents. Even though Communication research cannot produce results with 100% accuracy, quantitative research demonstrates patterns of human communication. Bryman, A., & Cramer, D. (2008). Quasi-experimental designs often suffer from increased selection bias. More information about qualitative research in both variants is available on an AIS-sponsored online resource. Quantitative Research. More objective and reliable. Figure 8 highlights that when selecting a data analysis technique, a researcher should make sure that the assumptions related to the technique are satisfied, such as normal distribution, independence among observations, linearity, and lack of multi-collinearity between the independent variables, and so forth (Mertens et al. Supported by artificial intelligence and 5G techniques in mobile information systems, the rich communication services (RCS) are emerging as new media outlets and conversational agents for both institutional and individual users in China, which inherit the advantages of the short messaging service (SMS) with larger coverage and higher reach rate. Cochran, W. G. (1977). One other caveat is that the alpha protection level can vary. The units are known so comparisons of measurements are possible. ), Measurement Errors in Surveys (pp. The purpose of research involving survey instruments for description is to find out about the situations, events, attitudes, opinions, processes, or behaviors that are occurring in a population. Neyman and Pearsons idea was a framework of two hypotheses: the null hypothesis of no effect and the alternative hypothesis of an effect, together with controlling the probabilities of making errors. Science, Technology, Engineering, . The importance of quantitative research is that it offers tremendous help in studying samples and populations. Straub, D. W. (1989). But statistical conclusion and internal validity are not sufficient, instrumentation validity (in terms of measurement validity and reliability) matter as well: Unreliable measurement leads to attenuation of regression path coefficients, i.e. Cambridge University Press. McShane, B. Figure 4 summarizes criteria and tests for assessing reliability and validity for measures and measurements. Experiments can take place in the laboratory (lab experiments) or in reality (field experiments). Consider that with alternative hypothesis testing, the researcher is arguing that a change in practice would be desirable (that is, a direction/sign is being proposed). In D. Avison & J. Pries-Heje (Eds. Fitting Covariance Models for Theory Generation. Beyond Significance Testing: Statistics Reform in the Behavioral Sciences (2nd ed.). As such, it represents an extension of univariate analysis of variance (ANOVA). STUDY f IMPORTANCE OF QUANTITATIVE RESEARCH IN DIFFERENT FIELDS 1. Information Systems Research, 18(2), 211-227. Often, the presence of numeric data is so dominant in quantitative methods that people assume that advanced statistical tools, techniques, and packages to be an essential element of quantitative methods. Antonakis, J., Bendahan, S., Jacquart, P., & Lalive, R. (2010). The easiest way to show this, perhaps, is through an example. QtPR is also not design research, in which innovative IS artifacts are designed and evaluated as contributions to scientific knowledge. It is not about fitting theory to observations. Scientific Research in Information Systems: A Beginners Guide (2nd ed.). Reliability is important to the scientific principle of replicability because reliability implies that the operations of a study can be repeated in equal settings with the same results. (1985). This video emphasized the Importance of quantitative research across various fields such as Science, Technology, Engineering, and Mathematics (STEM), Account. For example, their method could have been some form of an experiment that used a survey questionnaire to gather data before, during, or after the experiment. Needless to say, this brief discussion only introduces three aspects to the role of randomization. Block, J. New York: John Wiley and Sons. The ability to explain any observation as an apparent verification of psychoanalysis is no proof of the theory because it can never be proven wrong to those who believe in it. Lee, A. S., & Hubona, G. S. (2009). In this technique, one or more independent variables are used to predict a single dependent variable. Norton & Company. American Council on Education. The resulting data is analyzed, typically through descriptive or inferential statistical techniques. Information and communication technology, or ICT, is defined as the combination of informatics . ), such that no interpretation, judgment, or personal impressions are involved in scoring. The Critical Role of External Validity in Organizational Theorizing. Rand McNally College Publishing Company. (2013). Manipulation validity is used in experiments to assess whether an experimental group (but not the control group) is faithfully manipulated and we can thus reasonably trust that any observed group differences are in fact attributable to the experimental manipulation. The measure used as a control variable the pretest or pertinent variable is called a covariate (Kerlinger, 1986). Stevens, J. P. (2001). Doll, W. J., & Torkzadeh, G. (1988). 2. Were it broken down into its components, there would be less room for criticism. Where quantitative research falls short is in explaining the 'why'. This common misconception arises from a confusion between the probability of an observation given the null probability (Observation t | H0) and the probability of the null given an observation probability (H0 | Observation t) that is then taken as an indication for p(H0). What is the importance of quantitative research in the field of engineering? (1951). No faults in content or design should be attributed to any persons other than ourselves since we made all relevant decisions on these matters. Another important debate in the QtPR realm is the ongoing discussion on reflective versus formative measurement development, which was not covered in this resource. This method is focused on the what question. NHST rests on the formulation of a null hypothesis and its test against a particular set of data. Consider, for example, that you want to score student thesis submissions in terms of originality, rigor, and other criteria. The objective is to find a way of condensing the information contained in a number of original variables into a smaller set of principal component variables with a minimum loss of information (Hair et al., 2010). The key point to remember here is that for validation, a new sample of data is required it should be different from the data used for developing the measurements, and it should be different from the data used to evaluate the hypotheses and theory. It incorporates techniques to demonstrate and assess the content validity of measures as well as their reliability and validity. Deduction is a form of logical reasoning that involves deriving arguments as logical consequences of a set of more general premises. (1960). Tests of content validity (e.g., through Q-sorting) are basically intended to verify this form of randomization. Limitation, recommendation for future works and conclusion are also included. Wasserstein, R. L., & Lazar, N. A. Straub, Boudreau, and Gefen (2004) introduce and discuss a range of additional types of reliability such as unidimensional reliability, composite reliability, split-half reliability, or test-retest reliability. Cohen, J. By continuing to navigate this site you are consenting to the collection of information via our use of cookies. Boudreau, M.-C., Gefen, D., & Straub, D. W. (2001). Use Omega Rather than Cronbachs Alpha for Estimating Reliability. Nowadays, when schools are increasingly transforming themselves into smart schools, the importance of educational technology also increases. In the vast majority of cases, researchers are not privy to the process so that they could reasonably assess this. If objects A and B are judged by respondents as being the most similar compared with all other possible pairs of objects, multidimensional scaling techniques will position objects A and B in such a way that the distance between them in the multidimensional space is smaller than the distance between any other two pairs of objects. A wonderful introduction to behavioral experimentation is Lauren Slaters book Opening Skinners Box: Great Psychological Experiments of the Twentieth Century (Slater, 2005). Gelman, A., & Stern, H. (2006). The p-value is not an indication of the strength or magnitude of an effect (Haller & Kraus, 2002). Wiley. An overview of endogeneity concerns and ways to address endogeneity issues through methods such as fixed-effects panels, sample selection, instrumental variables, regression discontinuity, and difference-in-differences models, is given by Antonakis et al. In contrast, correlations are about the effect of one set of variables on another. Three Roles for Statistical Significance and the Validity Frontier in Theory Testing. 1SAGE Research Methods, Quantitative Research, Purpose of in 2017, 2Scribbr, An Introduction to Quantitative Research in February 2021, 3WSSU, Key Elements of a Research Proposal Quantitative Design, 4Formplus, 15 Reasons To Choose Quantitative Over Qualitative Research in July 2020. Bivariate analyses concern the relationships between two variables. This resource is dedicated to exploring issues in the use of quantitative, positivist research methods in Information Systems (IS). If researchers fail to ensure shared meaning between their socially constructed theoretical constructs and their operationalizations through measures they define, an inherent limit will be placed on their ability to measure empirically the constructs about which they theorized. How important is quantitative research to communication? Misinterpretations of Significance: A Problem Students Share with Their Teachers? Specifically, the objective is to classify a sample of entities (individuals or objects) into a smaller number of mutually exclusive groups based on the similarities among the entities (Hair et al., 2010). Investigating Two Contradictory Views of Formative Measurement in Information Systems Research. Predictive validity (Cronbach & Meehl, 1955) assesses the extent to which a measure successfully predicts a future outcome that is theoretically expected and practically meaningful. One of the main reasons we were interested in maintaining this online resource is that we have already published a number of articles and books on the subject. Starting at the Beginning: An Introduction to Coefficient Alpha and Internal Consistency. Researchers typically use quantitative data when the objective of their study is to assess a problem or answer the what or how many of a research question. It is also vital because many constructs of interest to IS researchers are latent, meaning that they exist but not in an immediately evident or readily tangible way. This is why we argue in more detail in Section 3 below that modern QtPR scientists have really adopted a post-positivist perspective. A new Criterion for Assessing Discriminant Validity in Variance-based Structural Equation Modeling. Test Validation. Interrater reliability is important when several subjects, researchers, raters, or judges code the same data(Goodwin, 2001). (2010) suggest that confirmatory studies are those seeking to test (i.e., estimating and confirming) a prespecified relationship, whereas exploratory studies are those that define possible relationships in only the most general form and then allow multivariate techniques to search for non-zero or significant (practically or statistically) relationships. Chin, W. W. (2001). 2004). Several threats are associated with the use of NHST in QtPR. Likely this is not the intention. ER models are highly useful for normalizing data, but do not serve well for social science research models. Reviewers should be especially honed in to measurement problems for this reason. Poppers contribution to thought specifically, that theories should be falsifiable is still held in high esteem, but modern scientists are more skeptical that one conflicting case can disprove a whole theory, at least when gauged by which scholarly practices seem to be most prevalent. ), there is no doubt mathematically that if the two means in the sample are not exactly the same number, then they are different. Levallet, N., Denford, J. S., & Chan, Y. E. (2021). Selection bias in turn diminishing internal validity. Oliver and Boyd. For example, each participant would first evaluate user-interface-design one, then the second user-interface-design, and then the third. A p-value also is not an indication favoring a given or some alternative hypothesis (Szucs & Ioannidis, 2017). As the transition was made to seeing communication from a social scientific perspective, scholars began studying communication using the methods established from the physical sciences. In this context, the objective of the research presented in this article was to identify . The typical way to set treatment levels would be a very short delay, a moderate delay and a long delay. A typical way this is done is to divide the subjects into groups randomly where each group is treated differently so that the differences in these treatments result in differences in responses across these groups as hypothesize. This post-positivist epistemology regards the acquisition of knowledge as a process that is more than mere deduction. It is also referred to as the maximum likelihood criterion or U statistic (Hair et al., 2010). This computation yields the probability of observing a result at least as extreme as a test statistic (e.g., a t value), assuming the null hypothesis of the null model (no effect) being true. This tactic relies on the so-called modus tollens (denying the consequence) (Cohen, 1994) a much used logic in both positivist and interpretive research in IS (Lee & Hubona, 2009). Figure 5 uses these distinctions to introduce a continuum that differentiates four main types of general research approaches to QtPR. It is used to describe the current status or circumstance of the factor being studied. Gaining experience in quantitative research enables professionals to go beyond existing findings and explore their area of interest through their own sampling, analysis and interpretation of the data. The number of such previous error terms determines the order of the moving average. Logit analysis is a special form of regression in which the criterion variable is a non-metric, dichotomous (binary) variable. (1970).
