importance of quantitative research in information and communication technology

For example, each participant would first evaluate user-interface-design one, then the second user-interface-design, and then the third. A quantitative investigation of the role of Information and Communication Technologies in the implementation of a product-service system January 2012 International Journal of Production. Any design error in experiments renders all results invalid. 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. Often, such tests can be performed through structural equation modelling or moderated mediation models. In fact, Cook and Campbell (1979) make the point repeatedly that QtPR will always fall short of the mark of perfect representation. The third stage, measurement testing and revision, is concerned with purification, and is often a repeated stage where the list of candidate items is iteratively narrowed down to a set of items that are fit for use. They may well be. Information Systems Research, 18(2), 211-227. MIS Quarterly, 40(3), 529-551. One caveat in this case might be that the assignment of treatments in field experiments is often by branch, office, or division and there may be some systematic bias in choosing these sample frames in that it is not random assignment. The moving average part adds a linear combination of the error terms of the previous observations. The simplest distinction between the two is that quantitative research focuses on numbers, and qualitative research focuses on text, most importantly text that captures records of what people have said, done, believed, or experienced about a particular phenomenon, topic, or event. Readers interested primarily in the practical challenges of QtPR might want to skip this section. In D. Avison & J. Pries-Heje (Eds. The conceptual labeling of this construct is too broad to easily convey its meaning. Koronadal City: Department of Education . Sage. Formative Versus Reflective Indicators in Organizational Measure Development: A Comparison and Empirical Illustration. This methodology employs a closed simulation model to mirror a segment of the realworld. Human subjects are exposed to this model and their responses are recorded. The most popular SEM methods include LISREL (Jreskog & Srbom, 2001) and equivalent software packages such as AMOS and Mplus, on the one hand, and Partial Least Squares (PLS) modeling (Chin, 2001; Hair et al., 2013), on the other hand. Quantitative Research is generally used in the field of community health, marketing, sociology,economics, psychology, demographics, gender studies, political science. Hair et al. Judd, C. M., Smith, E. R., & Kidder, L. H. (1991). For example, one key aspect in experiments is the choice of between-subject and within-subject designs: In between-subject designs, different people test each experimental condition. Available Formats High ecological validity means researchers can generalize the findings of their research study to real-life settings. Fisher introduced the idea of significance testing involving the probability p to quantify the chance of a certain event or state occurring, while Neyman and Pearson introduced the idea of accepting a hypothesis based on critical rejection regions. Myers, M. D. (2009). A second big problem is the inappropriate design of treatment and tasks. The American Statistician, 70(2), 129-133. While this is often true, quantitative methods do not necessarily involve statistical examination of numbers. If they omit measures, the error is one of exclusion. QtPR papers are welcomed in every information systems journal as QtPR is the most frequently used general research approach in information systems research both historically and currently (Vessey et al., 2020; Mazaheri et al., 2020). Levallet, N., Denford, J. S., & Chan, Y. E. (2021). And, yet both uncertainty (e.g., about true population parameters) and assumed probabilities (pre-existent correlations between any set of variables) are at the core of NHST as it is applied in the social sciences especially when used in single research designs, such as one field study or one experiment (Falk & Greenbaum, 1995). Correspondence analysis is a recently developed interdependence technique that facilitates both dimensional reduction of object ratings (e.g., products, persons, etc.) This is a quasi-experimental research methodology that involves before and after measures, a control group, and non-random assignment of human subjects. One of the advantages of SEM is that many methods (such as covariance-based SEM models) cannot only be used to assess the structural model the assumed causation amongst a set of multiple dependent and independent constructs but also, separately or concurrently, the measurement model the loadings of observed measurements on their expected latent constructs. Communications of the Association for Information Systems, 8(9), 141-156. In D. Avison & J. Pries-Heje (Eds. It differs from construct validity, in that it focuses on alternative explanations of the strength of links between constructs whereas construct validity focuses on the measurement of individual constructs. Falsification and the Methodology of Scientific Research Programs. Sira Vegas and colleagues (Vegas et al., 2016) discuss advantages and disadvantages between a wide range of experiment designs, such as independent measures, repeated measures, crossover, matched-pairs, and different mixed designs. 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. In E. Mumford, R. Hirschheim, & A. T. Wood-Harper (Eds. Qualitative research emphasizes understanding of phenomena through direct observation, communication with participants, or analyses of texts, and at times stress contextual subjective accuracy over generality. What are theories? Too Big to Fail: Large Samples and the p-Value Problem. (2019). The growth and the development of technology are playing an important role in higher education. Estimation and Inference in Econometrics. A Post-Positivist Answering Back. It is used to describe the current status or circumstance of the factor being studied. MIS Quarterly, 35(2), 261-292. Multiple regression is the appropriate method of analysis when the research problem involves a single metric dependent variable presumed to be related to one or more metric independent variables. MIS Quarterly, 33(4), 689-708. Researchers using field studies typically do not manipulate independent variables or control the influence of confounding variables (Boudreau et al., 2001). We can have correlational associated or correlational predictive designs. Senate Budget Amendments 3-25-2015. This is not the most recent version, view other versions 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. (1994). For example, one way to analyze time-series data is by means of the Auto-Regressive Integrated Moving Average (ARIMA) technique, that captures how previous observations in a data series determine the current observation. It involves deducing a conclusion from a general premise (i.e., a known theory), to a specific instance (i.e., an observation). The purpose of quantitative research is to attain greater knowledge and understanding of the social world. Journal of the Royal Statistical Society. A new Criterion for Assessing Discriminant Validity in Variance-based Structural Equation Modeling. A seminal book on experimental research has been written by William Shadish, Thomas Cook, and Donald Campbell (Shadish et al., 2001). Management Science, 29(5), 530-545. Researchers can clearly communicate quantitative results using unbiased statistics. They should create . PLS-Graph users guide. Experimentation in Software Engineering: An Introduction. On The Social Psychology of the Psychological Experiment: With Particular Reference to Demand Characteristics and their Implications. . Wasserstein, R. L., Schirm, A. L., & Lazar, N. A. Next we did the other thing Such sentences stress the actions and activities of the researcher(s) rather than the purposes of these actions. Bryman, A., & Cramer, D. (2008). Nosek, B. QtPR describes a set of techniques to answer research questions with an emphasis on state-of-the-art analysis of quantitative data, that is, types of data whose value is measured in the form of numbers, with a unique numerical value associated with each data set. In research concerned with confirmation, problems accumulate from the left to the right of Figure 2: If researchers fail to ensure shared meaning between their theoretical constructs and operationalizations, this restricts their ability to measure faithfully the constructs they theorized. Statistical Power Analysis for the Behavioral Sciences (2nd ed.). As noted above, the logic of NHST demands a large and random sample because results from statistical analyses conducted on a sample are used to draw conclusions about the population, and only when the sample is large and random can its distribution assumed to be a normal distribution. Stationarity means that the mean and variance remain the same throughout the range of the series. If they are randomly assigned, then there is a low probability that the effect is caused by any factors other than the treatment. Often, a small p-value is considered to indicate a strong likelihood of getting the same results on another try, but again this cannot be obtained because the p-value is not definitely informative about the effect itself (Miller, 2009). A treatment is a manipulation of the real world that an experimenter administers to the subjects (also known as experimental units) so that the experimenter can observe a response. The monitoring and measurement of physical ICT system performances are crucial to assess the computer processing unit (CPU) load, the available memory, the used bandwidth, and so on to guarantee the ICT-based services correctly work regarding their expected use. Lehmann, E. L. (1993). Quantitative research seeks to establish knowledge through the use of numbers and measurement. When authors say their method was a survey, for example, they are telling the readers how they gathered the data, but they are not really telling what their method was. As an example, Henseler et al. The field of information technology is one of the most recent developments of the 21st century. Discovering Statistics using IBM SPSS Statistics. Faced with the volume of academic output, studies that present a descriptive character are necessary. Evermann, J., & Tate, M. (2011). Accordingly, a scientific theory is, at most, extensively corroborated, which can render it socially acceptable until proven otherwise. R-squared is derived from the F statistic. Information Systems Research, 24(4), 906-917. (1951). Dunning, T. (2012). ), Criticism and the Growth of Knowledge (pp. Another debate in QtPR is about the choice of analysis approaches and toolsets. Laboratory Experimentation. Lauren Slater provides some wonderful examples in her book about experiments in psychology (Slater, 2005). All measures in social sciences, thus, are social constructions that can only approximate a true, underlying reality. Gefen, D., Ben-Assuli, O., Stehr, M., Rosen, B., & Denekamp, Y. One benefit of a high-quality education is learning the purposes and advantages of the various methodologies and how to apply them in your own research. In a correlational study, variables are not manipulated. Cronbach, L. J. Elsevier. (2011) provide several recommendations for how to specify the content domain of a construct appropriately, including defining its domain, entity, and property. 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). Cambridge University Press. The p-value is not an indication of the strength or magnitude of an effect (Haller & Kraus, 2002). Different types of reliability can be distinguished: Internal consistency (Streiner, 2003) is important when dealing with multidimensional constructs. Our development and assessment of measures and measurements (Section 5) is another simple reflection of this line of thought. An example would be the correlation between salary increases and job satisfaction. (1972). Kerlinger, F. N. (1986), Foundations of Behavioral Research, Harcourt Brace Jovanovich. Graphically, a multinormal distribution of X1 and X2 will resemble a sheet of paper with a weight at its center, the center being analogous to the mean of the joint distribution. Different methods in each tradition are available and are typically available in statistics software applications such as Stata, R, SPSS, or others. (Wikipedia.org). To analyze data with a time dimension, several analytical tools are available that can be used to model how a current observation can be estimated by previous observations, or to forecast future observations based on that pattern. Quantitative studies are often fast, focused, scientific and relatable.4. Social scientists, including communication researchers, use quantitative research to observe phenomena or occurrences that affect individuals. In fact, there are several ratings that we can glean from the platform and these we will combine to create an aggregate score. A. The Effect of Big Data on Hypothesis Testing. Hayesa, A. F. and Coutts, J. J. We typically have multiple reviewers of such thesis to approximate an objective grade through inter-subjective rating until we reach an agreement. Guo, W., Straub, D. W., & Zhang, P. (2014). Quantitative studies are focused. And since the results of field experiments are more generalizable to real-life settings than laboratory experiments (because they occur directly within real-life rather than artificial settings), they score also relatively high on external validity. If youre wondering about all but dissertation (ABD) status, then youre likely already a doctoral student or youre thinking about heading back to school to earn your terminal degree. QtPR is also not design research, in which innovative IS artifacts are designed and evaluated as contributions to scientific knowledge. Because developing and assessing measures and measurement is time-consuming and challenging, researchers should first and always identify existing measures and measurements that have already been developed and assessed, to evaluate their potential for reuse. If multiple measurements are taken, reliable measurements should all be consistent in their values. Accounting principles try to control this, but, as cases like Enron demonstrate, it is possible for reported revenues or earnings to be manipulated. We can know things statistically, but not deterministically. Hedges, L. V., & Olkin, I. Kaplan, B., and Duchon, D. Combining Qualitative and Quantitative Methods in Information Systems Research: A Case Study, MIS Quarterly (12:4 (December)) 1988, pp. Coombs, C. H. (1976). Cambridge University Press. NHST originated from a debate that mainly took place in the first half of the 20th century between Fisher (e.g., 1935a, 1935b; 1955) on the one hand, and Neyman and Pearson (e.g., 1928, 1933) on the other hand. It highlights different impacts of information and communication technology for providing development to generate different methods. Cohen, J. This kind of research is commonly used in science fields such as sociology, psychology, chemistry and physics. The emphasis in sentences using the personal pronouns is on the researcher and not the research itself. This demarcation of science from the myths of non-science also assumes that building a theory based on observation (through induction) does not make it scientific. Malignant Side Effects of Null-hypothesis Significance Testing. Likely this is not the intention. Diamantopoulos, Adamantios and Heidi M. Winklhofer, Index Construction with Formative Indicators: An Alternative to Scale Development, Journal of Marketing Research, 38, 2, (2001), 269-277. Induction and introspection are important, but only as a highway toward creating a scientific theory. Hence, r values are all about correlational effects whereas p-values are all about sampling (see below). QtPR has historically relied on null hypothesis significance testing (NHST), a technique of statistical inference by which a hypothesized value (such as a specific value of a mean, a difference between means, correlations, ratios, variances, or other statistics) is tested against a hypothesis of no effect or relationship on basis of empirical observations (Pernet, 2016). Cochran, W. G. (1977). Descriptive and correlational research usually involves non-experimental, observational data collection techniques, such as survey instruments, which do not involve controlling or manipulating independent variables. Cohen, J. This notion that scientists can forgive instances of disproof as long as the bulk of the evidence still corroborates the base theory lies behind the general philosophical thinking of Imre Lakatos (1970). There are different types of validity that are important to identify. Variables are not manipulated in this type of research and researchers do not use the law of probability. B., Poole, C., Goodman, S. N., & Altman, D. G. (2016). While these views do clearly differ, researchers in both traditions also agree on several counts. Any sources cited were Importance of ICT Information and Communication Technology (ICT) is a blanket term encompassing all the technologies and services involved in computing, data management, telecommunications provision, and the internet. The Critical Role of External Validity in Organizational Theorizing. 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). Other techniques include OLS fixed effects and random effects models (Mertens et al., 2017). Springer. Testing internal consistency, i.e., verifying that there are no internal contradictions. Human Relations, 61(8), 1139-1160. Only that we focus here on those genres that have traditionally been quite common in our field and that we as editors of this resource feel comfortable in writing about. Models and prototypes are frequently the products of design research. (1991). Econometric Analysis (7th ed.). The term research instrument can be preferable to specific names such as survey instruments in many situations. We might say that archival data might be reasonably objective, but it is not purely objective By any stretch of the imagination. But as with many other concepts, one should note that other characterizations of content validity also exist (e.g., Rossiter, 2011). Figure 2 describes in simplified form the QtPR measurement process, based on the work of Burton-Jones and Lee (2017). Integrated communications and technology (ICT) encompasses both . The difference is that there is either no control group, no random selection or no active manipulation variable. European Journal of Information Systems, 4, 74-81. So, essentially, we are testing whether our obtained data fits previously established causal models of the phenomenon including prior suggested classifications of constructs (e.g., as independent, dependent, mediating, or moderating). One can infer the meaning, characteristics, motivations, feelings and intentions of others on the basis of observations (Kerlinger, 1986). The easiest way to show this, perhaps, is through an example. Ringle, C. M., Sarstedt, M., & Straub, D. W. (2012). Journal of Management Information Systems, 19(2), 129-174. This methodology is primarily concerned with the examination of historical documents. It is not about fitting theory to observations. Avoiding personal pronouns can likewise be a way to emphasize that QtPR scientists were deliberately trying to stand back from the object of the study. What Is This Thing Called Science? Internal validity assesses whether alternative explanations of the dependent variable(s) exist that need to be ruled out (Straub, 1989). This model suggests that the underlying view that leads a scholar to conclude that QtPR can produce knowledge is that the world has an objective reality that can be captured and translated into models that imply testable hypotheses, usually in the form of statistical or other numerical analyses. Random selection is about choosing participating subjects at random from a population of interest. Annual Review of Psychology, 60, 577-605. The choice of the correct analysis technique is dependent on the chosen QtPR research design, the number of independent and dependent (and control) variables, the data coding and the distribution of the data received. Our argument, hence, is that IS researchers who work with quantitative data are not truly positivists, in the historical sense. Investigate current theories or trends surrounding the problem or issue. 221-238). ), Research Methods in Information Systems (pp. Then I did something else. Or we did this, followed by our doing that. The issue is not whether the delay times are representative of the experience of many people. After observing the situation to be investigated, the researcher forms a hypothesis and then uses deductive reasoning by predicting how the data should look if the hypothesis is true, after collecting the data and analyzing it to confirm or rejectthe hypothesis. Knowledge is acquired through both deduction and induction. Moving from the left (theory) to the middle (instrumentation), the first issue is that of shared meaning. Goodwin, L. D. (2001). In attempting to falsify the theory or to collect evidence in support of that theory, operationalizations in the form of measures (individual variables or statement variables) are needed and data needs to be collected from empirical referents (phenomena in the real world that the measure supposedly refers to). Quantitative Research in the field of business is significant because through statistical methods, high possibilities of risk can be prevented. Organizational Research Methods, 13(4), 668-689. If they do not segregate or differ from each other as they should, then it is called a discriminant validity problem. On Making Causal Claims: A Review and Recommendations. Example: the study of DSWD . (2014) point out, even extremely weak effects of r = .005 become statistically significant at some level of N and in the case of regression with two IVs, this result becomes statistically significant for all levels of effect size at a N of only 500. Their paper presents the arguments for why various forms of instrumentation validity should be mandatory and why others are optional. Finally, governmental data is certainly subject to imperfections, lower quality data that the researcher is her/himself unaware of. Glaser, B. G., & Strauss, A. L. (1967).
