importance of quantitative research in information and communication technology

A Primer on Partial Least Squares Structural Equation Modeling (PLS-SEM). Technologies like Artificial Intelligence and Machine Learning have taken business communication to a whole new level. Consider the following: You are testing constructs to see which variable would or could confound your contention that a certain variable is as good an explanation for a set of effects. (2014). 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. Lee, A. S., & Hubona, G. S. (2009). An unreliable way of measuring weight would be to ask onlookers to guess a persons weight. Of special note is the case of field experiments. 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. 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. Since the data is coming from the real world, the results can likely be generalized to other similar real-world settings. They involve manipulations in a real world setting of what the subjects experience. Integral to this approach is the search for a quantitative, predictive, multilevel, theoretical conceptual framework that both If multiple measurements are taken, reliable measurements should all be consistent in their values. More details on measurement validation are discussed in Section 5 below. QtPR is also not design research, in which innovative IS artifacts are designed and evaluated as contributions to scientific knowledge. Overall, modern social scientists favor theorizing models with expressed causal linkages and predictions of correlational signs. And it is possible using the many forms of scaling available to associate this construct with market uncertainty falling between these end points. A linear regression attempts determine the best equation describing a set of x and y data points, by using an optimization function such as least squares or maximum likelihood. Wohlin et al.s (2000) book on Experimental Software Engineering, for example, illustrates, exemplifies, and discusses many of the most important threats to validity, such as lack of representativeness of independent variable, pre-test sensitisation to treatments, fatigue and learning effects, or lack of sensitivity of dependent variables. Experimental and Quasi-Experimental Designs for Generalized Causal Inference (2nd ed.). Recker, J. Q-sorting offers a powerful, theoretically grounded, and quantitative tool for examining opinions and attitudes. Information Systems Research, 32(1), 130146. The second cornerstone is an emphasis on (post-)positivist philosophy. B. Woszczynski (Eds. Davis, F. D. (1989). Kaplowitz, M. D., Hadlock, T. D., & Levine, R. (2004). The experimental hypothesis was that the work group with better lighting would be more productive. WebFreelance. This difference stresses that empirical data gathering or data exploration is an integral part of QtPR, as is the positivist philosophy that deals with problem-solving and the testing of the theories derived to test these understandings. Hackett. The aim of spatial analysis is to understand differences across space rather than regularities. Any design error in experiments renders all results invalid. WebSupported by artificial intelligence and 5G techniques in mobile information systems, the rich communication services (RCS) are emerging as new media outlets and Of course, such usage of personal pronouns occurs in academic writing, but what it implies might distract from the main storyline of a QtPR article. Aguirre-Urreta, M. I., & Marakas, G. M. (2012). Understanding and addressing these challenges are important, independent from whether the research is about confirmation or exploration. Myers, M. D. (2009). the Arts Council or ACE). Mathematically, what we are doing in statistics, for example in a t-test, is to estimate the probability of obtaining the observed result or anything more extreme in the available sample data than that was actually observed, assuming that (1) the null hypothesis holds true in the population and (2) all underlying model and test assumptions are met (McShane & Gal, 2017). Kline, R. B. Similarly, the choice of data analysis can vary: For example, covariance structural equation modeling does not allow determining the cause-effect relationship between independent and dependent variables unless temporal precedence is included. (2001) distinguish three factors of internal validity, these being (1) temporal precedence of IVs before DVs; (2) covariation; and (3) the ability to show the predictability of the current model variables over other, missing variables (ruling out rival hypotheses). Block, J. Nosek, B. Figure 2 describes in simplified form the QtPR measurement process, based on the work of Burton-Jones and Lee (2017). When the sample size n is relatively small but the p-value relatively low, that is, less than what the current conventional a-priori alpha protection level states, the effect size is also likely to be sizeable.

The units are known so comparisons of measurements are possible. Eddingtons eclipse observation was a make-or-break event for Einsteins theory. As this discussion already illustrates, it is important to realize that applying NHST is difficult. Typically, QtPR starts with developing a theory that offers a hopefully insightful and novel conceptualization of some important real-world phenomena. Zeitschrift fr Physik, 43(3-4), 172-198. An example might help to explain this. WebUnderstanding and addressing these challenges are important, independent from whether the research is about confirmation or exploration. One of the most common issues in QtPR papers is mistaking data collection for method(s). Theory and Reality: An Introduction to the Philosophy of Science. Hempel, C. G. (1965). Academic Press. Evidence suggests that teachers in rural secondary schools are still unclear about how to use technology appropriately to facilitate particular approaches 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). Scandinavian Journal of Information Systems, 22(2), 3-30. Another debate concerns alternative models for reasoning about causality (Pearl, 2009; Antonakis et al., 2010; Bollen & Pearl, 2013) based on a growing recognition that causality itself is a socially constructed term and many statistical approaches to testing causality are imbued with one particular philosophical perspective toward causality. In this perspective, QtPR methods lie on a continuum from study designs where variables are merely observed but not controlled to study designs where variables are very closely controlled. (1989) Structural Equations with Latent Variables.

There are different types of validity that are important to identify. Face-to-face or telephone interviews can provide a lot of insight into your target audience. However, this is a happenstance of the statistical formulas being used and not a useful interpretation in its own right. If the single dependent variable is dichotomous (e.g., male-female) or multichotomous (e.g., high-medium-low) and therefore non-metric, the multivariate technique of multiple discriminant analysis (MDA) is appropriate. In Poppers falsification view, for example, one instance of disconfirmation disproves an entire theory, which is an extremely stringent standard. The Nature of Theory in Information Systems. Systems-thinking in aviation. Suffice it to say at this point that in experiments, it is critical that the subjects are manipulated by the treatments and, conversely, that the control group is not manipulated. Multitrait-multimethod (MTMM) uses a matrix of correlations representing all possible relationships between a set of constructs, each measured by the same set of methods. In P. P. Biemer, R. M. Groves, L. E. Lyberg, N. A. Mathiowetz, & S. Sudman (Eds. One of the most prominent current examples is certainly the set of Bayesian approaches to data analysis (Evermann & Tate, 2014; Gelman et al., 2013; Masson, 2011). (1988). Only then, based on the law of large numbers and the central limit theorem can we upheld (a) a normal distribution assumption of the sample around its mean and (b) the assumption that the mean of the sample approximates the mean of the population (Miller & Miller 2012). We note that at other times, we have discussed ecological validity as a form of external validity (Im & Straub, 2015). A wonderful introduction to behavioral experimentation is Lauren Slaters book Opening Skinners Box: Great Psychological Experiments of the Twentieth Century (Slater, 2005). Like the theoretical research model of construct relationships itself, they are intended to capture the essence of a phenomenon and then to reduce it to a parsimonious form that can be operationalized through measurements. The standard value for betas has historically been set at .80 (Cohen 1988). Finally, ecological validity (Shadish et al., 2001) assesses the ability to generalize study findings from an experimental setting to a set of real-world settings. In Malaysia, ICT is considered as one of the main elements in transforming the country to the future development. This pure positivist attempt at viewing scientific exploration as a search for the Truth has been replaced in recent years with the recognition that ultimately all measurement is based on theory and hence capturing a truly objective observation is impossible (Coombs, 1976). It aims to be objective. 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). Problems with construct validity occur in three major ways. This paper focuses on the linkage between ICT and output growth. Others require coding, recoding, or transformation of the original data gathered through the collection technique. 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. Complex systems prone to dynamic events Vegas, S., Apa, C., & Juristo, N. (2016). 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. Harper and Row. 221-238). Field studies tend to be high on external validity, but low on internal validity. In scientific, quantitative research, we have several ways to assess interrater reliability. Findings can be evaluated using statistical analysis. 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. Information literacy is the set of skills needed to find, Random item inclusion means assuring content validity in a construct by drawing randomly from the universe of all possible measures of a given construct. 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. In LISREL, the equivalent statistic is known as a squared multiple correlation. Quantitative studies of science and technology represent the research field of utilization of mathematical, statistical, and data-analytical methods and techniques for gathering, handling, interpreting, and predicting a variety of features of the science and technology enterprise, such as performance, development, and dynamics. The guidelines consist of three sets of recommendations: two to encourage (should do and could do) and one to discourage (must not do) practices. 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.

One such example of a research method that is not covered in any detail here would be meta-analysis. WebThe relationship between technology and communication can be studied analytically at any time in human history. There are also articles on how information systems builds on these ideas, or not (e.g., Siponen & Klaavuniemi, 2020). 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. It is data that is codified, meaning: It has an amount that can be directly measured. NHST rests on the formulation of a null hypothesis and its test against a particular set of data. Most QtPR research involving survey data is analyzed using multivariate analysis methods, in particular structural equation modelling (SEM) through either covariance-based or component-based methods. The treatments always precede the collection of the DVs. ), there is no doubt mathematically that if the two means in the sample are not exactly the same number, then they are different. Development And Measurement Validity Of A Task-Technology Fit Instrument For User Evaluations Of Information Systems. 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. Central to understanding this principle is the recognition that there is no such thing as a pure observation. Miller, J. This methodology is similar to experimental simulation, in that with both methodologies the researcher designs a closed setting to mirror the real world and measures the response of human subjects as they interact within the system. It examines the covariance structures of the variables and variates included in the model under consideration. Likely this is not the intention. Mohajeri, K., Mesgari, M., & Lee, A. S. (2020). Boudreau, M.-C., Gefen, D., & Straub, D. W. (2001). Journal of the Association for Information Systems, 19(8), 752-774. In fact, those who were not aware, depending on the nature of the treatments, may be responding as if they were assigned to the control group. Most of these analyses are nowadays conducted through statistical software packages such as SPSS, SAS, or mathematical programming environments such as R or Mathematica. If you are interested in different procedural models for developing and assessing measures and measurements, you can read up on the following examples that report at some lengths about their development procedures: (Bailey & Pearson, 1983; Davis, 1989; Goodhue, 1998; Moore & Benbasat, 1991; Recker & Rosemann, 2010; Bagozzi, 2011). 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. That is, in social reality, no two variables are ever perfectly unrelated (Meehl, 1967). Ringle, C. M., Sarstedt, M., & Straub, D. W. (2012). The impact of technology on communication is remarkable as with new tools and solutions emerging every day, it is continuing to transform the way businesses communicate. Accordingly, a scientific theory is, at most, extensively corroborated, which can render it socially acceptable until proven otherwise. The easiest way to show this, perhaps, is through an example. Communications of the Association for Information Systems, 12(2), 23-47. (2009). Statistical compendia, movie film, printed literature, audio tapes, and computer files are also widely used sources. With canonical analysis the objective is to correlate simultaneously several metric dependent variables and several metric independent variables. If your instrumentation is not acceptable at a minimal level, then the findings from the study will be perfectly meaningless. Sage.
