Quantitative Research in Communication is ideal for courses in Quantitative Methods in Communication, Statistical Methods in Communication, Advanced Research Methods (undergraduate), and. Elsevier. Management Science, 62(6), 1707-1718. Quantitative research is focused specifically on numerical information. MIS Quarterly, 25(1), 1-16. It incorporates techniques to demonstrate and assess the content validity of measures as well as their reliability and validity. It measures whether several measurement items that propose to measure the same general construct produce similar scores. This kind of research is commonly used in science fields such as sociology, psychology, chemistry and physics. A common theme is the importance of understanding the quantifiable . In I. Lakatos & A. Musgrave (Eds. Randomizing the treatment times, however, allows a scholar to generalize across the whole range of delays, hence increasing external validity within the same, alternatively designed study. All data are examined ex-post-facto by the researcher (Jenkins, 1985). Sarker, S., Xiao, X., Beaulieu, T., & Lee, A. S. (2018). Still, it should be noted that design researchers are increasingly using QtPR methods, specifically experimentation, to validate their models and prototypes so QtPR is also becoming a key tool in the arsenal of design science researchers. Garcia-Prez, M. A. Idea Group Publishing. The reason Einsteins theory was accepted was because it was put to the test: Eddingtons eclipse observation in 1919 confirmed its predictions, predictions that were in contrast to what should have been seen according to Newtonian physics. (2020). Controlling for Lexical Closeness in Survey Research: A Demonstration on the Technology Acceptance Model. Scientific Software International. In this context, the objective of the research presented in this article was to identify . In contrast, correlations are about the effect of one set of variables on another. Neyman, J., & Pearson, E. S. (1928). 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). Field studies are non-experimental inquiries occurring in natural systems. Bayesian approaches are essentially model selection procedures that compute a comparison between competing hypotheses or models, and where available knowledge about parameters in a statistical model is updated with the information in observed data. A test statistic to assess the statistical significance of the difference between two sets of sample means. Cronbach, L. J. Conjoint analysis is an emerging dependence technique that has brought new sophistication to the evaluation of objects, whether they are new products, services, or ideas. We are all post-positivists. Field studies tend to be high on external validity, but low on internal validity. Often, we approximate objective data through inter-subjective measures in which a range of individuals (multiple study subjects or multiple researchers, for example) all rate the same observation and we look to get consistent, consensual results. STUDY f IMPORTANCE OF QUANTITATIVE RESEARCH IN DIFFERENT FIELDS 1. Detmar STRAUB, David GEFEN, and Jan RECKER. We have co-authored a set of updated guidelines for quantitative researchers for dealing with these issues (Mertens & Recker, 2020). For example, statistical conclusion validity tests the inference that the dependent variable covaries with the independent variable, as well as that of any inferences regarding the degree of their covariation (Shadish et al., 2001). 221-238). The variables that are chosen as operationalizations to measure a theoretical construct must share its meaning (in all its complexity if needed). Sampling Techniques (3rd ed.). The difficulty in such analyses is to account for how events unfolding over time can be separated from the momentum of the past itself. But as with many other concepts, one should note that other characterizations of content validity also exist (e.g., Rossiter, 2011). One of the most common issues in QtPR papers is mistaking data collection for method(s). On the other hand, field experiments typically achieve much higher levels of ecological validity whilst also ensuring high levels of internal validity. (1989) Structural Equations with Latent Variables. Nosek, B. Here are some examples of studies conducted in educational settings using the above research methodologies:3, Quantitative researchers aim to create a general understanding of behavior and other phenomena across different settings and populations. It stood for garbage in, garbage out. It meant that if the data being used for a computer program were of poor, unacceptable quality, then the output report was just as deficient. The basic procedure of a quantitative research design is as follows:3, GCU supports four main types of quantitative research approaches: Descriptive, correlational, experimental and comparative.4. Hair et al. 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. Think of students sitting in front of a computer in a lab performing experimental tasks or think of rats in cages that get exposed to all sorts of treatments under observation. Figure 2 describes in simplified form the QtPR measurement process, based on the work of Burton-Jones and Lee (2017). A Guide To Becoming a Medical and Health Services Manager, 3300 West Camelback Road - Phoenix, AZ 85017, Criminal Justice, Government & Public Administration, Key Elements of a Research Proposal Quantitative Design, 15 Reasons To Choose Quantitative Over Qualitative Research. (1994). The Logic of Scientific Discovery. 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. Elden, M., & Chisholm, R. F. (1993). (2001) and Trochim et al. Education can be used in measuring the level of performance of students as well as teachers, and in assessing the effectiveness of the methods and the different programs conducted. By their very nature, experiments have temporal precedence. 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. The Logic of Inductive Inference. Some of them relate to the issue of shared meaning and others to the issue of accuracy. It highlights different impacts of information and communication technology for providing development to generate different methods. The measure used as a control variable the pretest or pertinent variable is called a covariate (Kerlinger, 1986). The ASAs Statement on P-values: Context, Process, and Purpose. (2021). As the name suggests, quantitative methods tend to specialize in quantities, in the sense that numbers are used to represent values and levels of measured variables that are themselves intended to approximate theoretical constructs. One aspect of this debate focuses on supplementing p-value testing with additional analysis that extra the meaning of the effects of statistically significant results (Lin et al., 2013; Mohajeri et al., 2020; Sen et al., 2022). ), Educational Measurement (2nd ed., pp. If your instrumentation is not acceptable at a minimal level, then the findings from the study will be perfectly meaningless. 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). For example, there is a longstanding debate about the relative merits and limitations of different approaches to structural equation modelling (Goodhue et al., 2007, 2012; Hair et al., 2011; Marcoulides & Saunders, 2006; Ringle et al., 2012), including alternative approaches such as Bayesian structural equation modeling (Evermann & Tate, 2014), or the TETRAD approach (Im & Wang, 2007). Quantitative Research is generally used in the field of community health, marketing, sociology,economics, psychology, demographics, gender studies, political science. 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. 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. This method focuses on comparisons. However, one should remember that the .05 and .20 thresholds are no more than an agreed-upon convention. 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. There are different types of validity that are important to identify. Straub, D. W., Gefen, D., Recker, J., Quantitative Research in Information Systems, Association for Information Systems (AISWorld) Section on IS Research, Methods, and Theories, last updated March 25, 2022, http://www.janrecker.com/quantitative-research-in-information-systems/. Epidemiology, 24(1), 69-72. (2016). Eddingtons eclipse observation was a make-or-break event for Einsteins theory. Meehl, P. E. (1967). (1960). Im, G., & Wang, J. In turn, there are theoretical assessments of validity (for example, for content validity,), which assess how well an operationalized measure fits the conceptual definition of the relevant theoretical construct; and empirical assessments of validity (for example, for convergent and discriminant validity), which assess how well collected measurements behave in relation to the theoretical expectations. Journal of Marketing Research, 18(1), 39-50. Cambridge University Press. More objective and reliable. Moving from the left (theory) to the middle (instrumentation), the first issue is that of shared meaning. The current ICT master plan for the Philippines dates back to 2006. Myers, M. D. (2009). 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. The importance of information communication technology, visual analysis, and web monitoring and control are all examples of Information Communication Technology (ICT). MIS Quarterly, 30(2), iii-ix. Analysis of covariance (ANCOVA) is a form of analysis of variance that tests the significanceof the differences among means of experimental groups after taking into account initial differences among the groups and the correlation of the initial measures and the dependent variable measures. (2000). Allows you get optimum efficiency and reliability. Human Relations, 61(8), 1139-1160. ), Research in Information Systems: A Handbook for Research Supervisors and Their Students (pp. 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. Therefore, QtPR can involve different techniques for data collection and analysis, just as qualitative research can involve different techniques for data collection (such as focus groups, case study, or interviews) and data analysis (such as content analysis, discourse analysis, or network analysis). (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. SEM has been widely used in social science research for the causal modelling of complex, multivariate data sets in which the researcher gathers multiple measures of proposed constructs. In physical and anthropological sciences or other distinct fields, quantitative research is methodical experimental research of noticeable events via analytical, numerical, or computational methods. Basically, experience can show theories to be wrong, but can never prove them right. In contrast, according to Popper, is Freuds theory of psychoanalysis which can never be disproven because the theory is sufficiently imprecise to allow for convenient explanations and the addition of ad hoc hypotheses to explain observations that contradict the theory. Statistical control variables are added to models to demonstrate that there is little-to-no explained variance associated with the designated statistical controls. If at an N of 15,000 (see Guo et al., 2014, p. 243), the only reason why weak t-values in all models are not supported is that there is likely a problem with the data itself. (1988). This can be the most immediate previous observation (a lag of order 1), a seasonal effect (such as the value this month last year, a lag of order 12), or any other combination of previous observations. Perceived Usefulness, Perceived Ease of Use, and User Acceptance of Information Technology. Surveys then allow obtaining correlations between observations that are assessed to evaluate whether the correlations fit with the expected cause and effect linkages. The only way to see that world, for Plato and Socrates, was to reason about it; hence, Platos philosophical dialecticism. (1955). Hence, positivism differentiates between falsification as a principle, where one negating observation is all that is needed to cast out a theory, and its application in academic practice, where it is recognized that observations may themselves be erroneous and hence where more than one observation is usually needed to falsify a theory. Qualitative interpretive researchers start out with the assumption that access to reality (given or socially constructed) is only through social constructions such as language, consciousness, and shared meanings. Journal of the Royal Statistical Society, 98(1), 39-82. MIS Quarterly, 44(2), 525-559. The speed and efficiency of the quantitative method are attractive to many researchers. Textbooks on survey research that are worth reading include Floyd Flowers textbook (Fowler, 2001) plus a few others (Babbie, 1990; Czaja & Blair, 1996). ), Criticism and the Growth of Knowledge (pp. Kaplowitz, M. D., Hadlock, T. D., & Levine, R. (2004). 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. In both lab and field experiments, the experimental design can vary (see Figures 6 and 7). Decide on a focus of study based primarily on your interests. Natural Experiments in the Social Sciences: A Design-Based Approach. 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. Research results are totally in doubt if the instrument does not measure the theoretical constructs at a scientifically acceptable level. I still check those, "Resubmitted two revisions today. How important is quantitative research to communication? There is a large variety of excellent resources available to learn more about QtPR. Harper and Row. (2013). The Effect of Statistical Training on the Evaluation of Evidence. In theory, it is enough, in Poppers way of thinking, for one observation that contradicts the prediction of a theory to falsify it and render it incorrect. Springer. This stage also involves assessing these candidate items, which is often carried out through expert panels that need to sort, rate, or rank items in relation to one or more content domains of the constructs. Communications of the Association for Information Systems, 16(45), 880-894. Pursuing Failure. The objective of multiple regression analysis is to predict the changes in the dependent variable in response to the changes in the several independent variables (Hair et al., 2010). It is necessary for decision makers like education ministers, school administrators, and educational institutions to be . Since field studies often involve statistical techniques for data analysis, the covariation criterion is usually satisfied. (2014). Straub, D. W., Boudreau, M.-C., & Gefen, D. (2004). Australasian Journal of Information Systems, 24, doi:10.3127/ajis.v24i0.2045. Editors Comments: PLS: A Silver Bullet? 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. Communication. Squaring the correlation r gives the R2, referred to as the explained variance. (1970). Opening Skinners Box: Great Psychological Experiments of the Twentieth Century. Basic Books. The ultimate goal for a company is to be able to utilize communication technology productively. Quantitative research is used by social scientists, including communication researchers, to observe phenomena or occurrences affecting individuals. (2019). With a large enough sample size, a statistically significant rejection of a null hypothesis can be highly probable even if an underlying discrepancy in the examined statistics (e.g., the differences in means) is substantively trivial. Research Methodologies and MIS Research. Equity issues. For more information on our cookie collection and use please visit our Privacy Policy. Typical examples of statistical control variables in many QtPR IS studies are measurements of the size of firm, type of industry, type of product, previous experience of the respondents with systems, and so forth. Traditionally, QtPR has been dominant in this second genre, theory-evaluation, although there are many applications of QtPR for theory-generation as well (e.g., Im & Wang, 2007; Evermann & Tate, 2011). Information Systems Research, 32(1), 130146. In any case, the researcher is motivated by the numerical outputs and how to imbue them with meaning. 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. Tabachnick, B. G., & Fidell, L. S. (2001). Sample size sensitivity occurs in NHST with so-called point-null hypotheses (Edwards & Berry, 2010), i.e., predictions expressed as point values. For example, the price of a certain stock over days weeks, months, quarters, or years. Comparing PLS to Regression and LISREL: A Response to Marcoulides, Chin, and Saunders. (2007). PLS (Partial Least Squares) path modeling: A second generation regression component-based estimation approach that combines a composite analysis with linear regression. 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 form of randomization (random assignment) relates to the use of treatments or manipulations (in experiments, most often) and is therefore an aspect of internal validity (Trochim et al., 2016). 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. Scientific Research in Information Systems: A Beginners Guide (2nd ed.). (2020). The easiest way to show this, perhaps, is through an example. (2017). f importance of quantitative research across fields research findings can affect people's lives, ways of doing things, laws, rules and regulations, as well as policies, The experimental hypothesis was that the work group with better lighting would be more productive. When Statistical Significance Is Not Enough: Investigating Relevance, Practical Significance and Statistical Significance. The integrated part of the model is included when there is a trend in the data, such as an increase over time, in which case the difference between the observations is calculated rather than modeling the actual observed values. Aside from reducing effort and speeding up the research, the main reason for doing so is that using existing, validated measures ensures comparability of new results to reported results in the literature: analyses can be conducted to compare findings side-by-side. necessarily reflect the official policy or position of Grand Canyon University. Moreover, real-world domains are often much more complex than the reduced set of variables that are being examined in an experiment. 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). Typically, QtPR starts with developing a theory that offers a hopefully insightful and novel conceptualization of some important real-world phenomena. Of course, in reality, measurement is never perfect and is always based on theory. Even the bottom line of financial statements is structured by human thinking. It is also important to regularly check for methodological advances in journal articles, such as (Baruch & Holtom, 2008; Kaplowitz et al., 2004; King & He, 2005). (1985). King, W. R., & He, J. Journal of the Association for Information Systems, 12(9), 632-661. To assist researchers, useful Respositories of measurement scales are available online. In Lakatos view, theories have a hard core of ideas, but are surrounded by evolving and changing supplemental collections of both hypotheses, methods, and tests the protective belt. In this sense, his notion of theory was thus much more fungible than that of Popper. 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. (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. This method is used to study relationships between factors, which are measured and recorded as research variables. Kline, R. B. Providing a strong conceptual orientation to techniques and procedures that range from the "moderately basic" to . In research concerned with exploration, problems tend to accumulate from the right to the left of Figure 2: No matter how well or systematically researchers explore their data, they cannot guarantee that their conclusions reflect reality unless they first take steps to ensure the accuracy of their data. Importantly, they can also serve to change directions in a field. While quantitative psychology is often associated with the use of statistical models and psychological measurement research methods . Too Big to Fail: Large Samples and the p-Value Problem. 443-507). Reviewers should be especially honed in to measurement problems for this reason. This value means that researchers assume a 20% risk (1.0 .80) that they are correct in their inference. Taking steps to obtain accurate measurements (the connection between real-world domain and the concepts operationalization through a measure) can reduce the likelihood of problems on the right side of Figure 2, affecting the data (accuracy of measurement). Most of these analyses are nowadays conducted through statistical software packages such as SPSS, SAS, or mathematical programming environments such as R or Mathematica. This idea introduced the notions of control of error rates, and of critical intervals. Advertisement Still have questions? Pearl, J. (1972). Information Systems Research, 18(2), 211-227. See for example: https://en.wikibooks.org/wiki/Handbook_of_Management_Scales. For any quantitative researcher, a good knowledge of these tools is essential. Branch, M. (2014). Hence interpreting the readings of a thermometer cannot be regarded as a pure observation but itself as an instantiation of theory. An alternative to Cronbach alpha that does not assume tau-equivalence is the omega test (Hayes and Coutts, 2020). This task can be carried out through an analysis of the relevant literature or empirically by interviewing experts or conducting focus groups. John Wiley and Sons. They should create . first of all, research is necessary and valuable in society because, among other things, 1) it is an important tool for building knowledge and facilitating learning; 2) it serves as a means in understanding social and political issues and in increasing public awareness; 3) it helps people succeed in business; 4) it enables us to disprove lies and
