3. The ASAs Statement on P-values: Context, Process, and Purpose. 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. Quantitative research is used by social scientists, including communication researchers, to observe phenomena or occurrences affecting individuals. 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). The easiest way to show this, perhaps, is through an example. Some concerns of using ICT are also included in this paper which encompasses: a) High learning curve, b) Revised expectation on researcher, c) Research by the convenient of big data, and d). Springer. An example might help to explain this. Thus the experimental instrumentation each subject experiences is quite different. Items or phrases in the instrumentation are not related in the way they should be, or they are related in the ways they should not be. 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. The study was conducted with senior prospective teachers studying in a department of secondary mathematics education. In the latter case, the researcher is not looking to confirm any relationships specified prior to the analysis, but instead allows the method and the data to explore and then define the nature of the relationships as manifested in the data. Journal of Information Technology, 37(3), 288300. IS research is a field that is primarily concerned with socio-technical systems comprising individuals and collectives that deploy digital information and communication technology for tasks in business, private, or social settings. (2011) provide several recommendations for how to specify the content domain of a construct appropriately, including defining its domain, entity, and property. A second form of randomization (random selection) relates to sampling, that is, the procedures used for taking a predetermined number of observations from a larger population, and is therefore an aspect of external validity (Trochim et al. Collect and process your data using one or more of the methods below. Ill start: (1/3)", "Very interesting thoughts. 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, 2010a). 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). For example, each participant would first evaluate user-interface-design one, then the second user-interface-design, and then the third. Hedges, L. V., & Olkin, I. MIS Quarterly, 40(3), 529-551. Objective: An overview of systematic reviews was conducted to develop a broad picture of the dimensions and indicators of nursing care that have the potential to be influenced by the use of ICTs. The Logic of Scientific Discovery. Several viewpoints pertaining to this debate are available (Aguirre-Urreta & Marakas, 2012; Centefelli & Bassellier, 2009; Diamantopoulos, 2001; Diamantopoulos & Siguaw, 2006; Diamantopoulos & Winklhofer, 2001; Kim et al., 2010; Petter et al., 2007). Then I did something else. Or we did this, followed by our doing that. It discusses in detail relevant questions, for instance, where did the data come from, where are the existing gaps in the data, how robust is it and what were the exclusions within the data research. In a quantitative degree program, you will learn how to: Interested in becoming a quantitative researcher? Selection bias means that individuals, groups, or other data has been collected without achieving proper randomization, thereby failing to ensure that the sample obtained is representative of the population intended to be analyzed. 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).

Communications of the Association for Information Systems, 34(77), 1481-1514. Frontiers in Human Neuroscience, 11(390), 1-21. R-squared is derived from the F statistic. In effect, researchers often need to make the assumption that the books, as audited, are accurate reflections of the firms financial health. Bollen, K. A., & Curran, P. J. It is also a good method to use when your audience is more receptive to results in the form of facts, graphs, charts and statistics. Others require coding, recoding, or transformation of the original data gathered through the collection technique. A Theory of Data. The term research instrument can be preferable to specific names such as survey instruments in many situations. B., & Gal, D. (2017). Journal of Socio-Economics, 33(5), 587-606. It summarizes findings in the literature on the contribution of information and communication technology to economic growth arising from capital deepening and increases in total factor productivity.

When it comes to advancing your nursing education, its important to explore all the options available to you. Researchers use quantitative methods to observe situations or events that affect people. (Wikipedia.org). Communications of the Association for Information Systems, 12(2), 23-47. Academic Press. Idea Group Publishing. Data Collection Methods and Measurement Error: An Overview. In simple terms, in QtPR it is often useful to understand theory as a lawlike statement that attributes causality to sets of variables, although other conceptions of theory do exist and are used in QtPR and other types of research (Gregor, 2006). If your prediction is confirmed, verify your results, draw your final conclusions and present your findings. Larsen, K. R. T., & Bong, C. H. (2016). Quantitative research seeks to establish knowledge through the use of numbers and measurement. Burton-Jones, A., Recker, J., Indulska, M., Green, P., & Weber, R. (2017). Other popular ways to analyze time-series data are latent variable models such as latent growth curve models, latent change score models, or bivariate latent difference score models (Bollen & Curran, 2006; McArdle, 2009). Hence interpreting the readings of a thermometer cannot be regarded as a pure observation but itself as an instantiation of theory. They have become more popular (and more feasible) in information systems research over recent years. 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. Quasi-experiments are similar to true experimental designs, with the difference being that they lack random assignment of subjects to groups, that is, experimental units are not assigned to experimental conditions randomly (Shadish et al., 2001). For this reason, they argue for a critical-realist perspective, positing that causal relationships cannot be perceived with total accuracy by our imperfect sensory and intellective capacities (p. 29). A more reliable way, therefore, would be to use a scale. Quantitative research has the goal of gaining a better understanding of the social world. Gefen, D., & Larsen, K. R. T. (2017). Antonakis, J., Bendahan, S., Jacquart, P., & Lalive, R. (2010). 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. Our knowledge about research starts from here because it will lead us to the path of changing the world. 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 Design of Experiments. We already noted above that quantitative, positivist research is really a shorthand for quantitative, post-positivist research. Whereas qualitative researchers sometimes take ownership of the concept of post-positivism, there is actually little quarrel among modern quantitative social scientists over the extent to which we can treat the realities of the world as somehow and truly objective. A brief history of the intellectual thought behind this may explain what is meant by this statement. 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. Logit analysis is a special form of regression in which the criterion variable is a non-metric, dichotomous (binary) variable. Likewise, QtPR methods differ in the extent to which randomization is employed during data collection (e.g., during sampling or manipulations). 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). The fact of the matter is that the universe of all items is quite unknown and so we are groping in the dark to capture the best measures. The goals and design of the study are determined from the beginning, and the research serves to test the initial theory and determine whether it is true or false. Three Roles for Statistical Significance and the Validity Frontier in Theory Testing. Findings can be generalized if your selection process is well designed and the test sample is an appropriate representation of the population being studied. Furthermore, it is almost always possible to choose and select data that will support almost any theory if the researcher just looks for confirming examples. While these views do clearly differ, researchers in both traditions also agree on several counts. Vessey, I., Ramesh, V., & Glass, R. L. (2002). Marcoulides, G. A., & Saunders, C. (2006). Note, however, that a mis-calibrated scale could still give consistent (but inaccurate) results. (1989) Structural Equations with Latent Variables. Churchill Jr., G. A. Hayesa, A. F. and Coutts, J. J. While modus tollens is logically correct, problems in its application can still arise. This reasoning hinges on power among other things.

Convergent and Discriminant Validation by the Multitrait- Multimethod Matrix, Psychological Bulletin (56:2, March) 1959, pp 81-105. At the heart of positivism is Karl Poppers dichotomous differentiation between scientific theories and myth. A scientific theory is a theory whose predictions can be empirically falsified, that is, shown to be wrong. An example would be the correlation between salary increases and job satisfaction. Quantitative research collects information from existing and potential customers using sampling methods and sending out online surveys, online polls, and questionnaires, for . * Explain briefly the importance or contribution of . Journal of the Association for Information Systems, 19(8), 752-774. A scientific theory, in contrast to psychoanalysis, is one that can be empirically falsified. Sometimes there is no alternative to secondary sources, for example, census reports and industry statistics. (2009). 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. Tests of nomological validity typically involve comparing relationships between constructs in a network of theoretical constructs with theoretical networks of constructs previously established in the literature and which may involve multiple antecedent, mediator, and outcome variables. The typical way to set treatment levels would be a very short delay, a moderate delay and a long delay. Crossover Designs in Software Engineering Experiments: Benefits and Perils. Journal of the Association for Information Systems, 21(4), 1072-1102. Im, G., & Wang, J. Construct Measurement and Validation Procedures in MIS and Behavioral Research: Integrating New and Existing Techniques. The quantitative methods acquired in a Sustainability Master's online combine information from various sources to create more informed predictions, while importantly providing the scientific reasoning to accurately describe what is known and what is not. Pearsons or Spearman correlations, or percentage agreement scores are also used (Goodwin, 2001). Written for communication students, Quantitative Research in Communication provides practical, user-friendly coverage of how to use statistics, how to interpret SPSS printouts, how to write results, and how to assess whether the assumptions of various procedures have been met. Researchers study groups that are pre-existing rather than created for the study. Henseler, J., Ringle, C. M., & Sarstedt, M. (2015). Another important debate in the QtPR realm is the ongoing discussion on reflective versus formative measurement development. Part 2: A Demo in R of the Importance of Enabling Replication in PLS and LISREL. Cohens (1960) coefficient Kappa is the most commonly used test. Cambridge University Press. Quantitative psychology is a branch of psychology developed using certain methods and approaches which are designed to answer empirical questions, such as the development of measurement models and factor analysis. There are numerous ways to assess construct validity (Straub, Boudreau, and Gefen, 2004; Gefen, Straub, and Boudreau, 2000; Straub, 1989). 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). Multivariate analyses, broadly speaking, refer to all statistical methods that simultaneously analyze multiple measurements on each individual or object under investigation (Hair et al., 2010); as such, many multivariate techniques are extensions of univariate and bivariate analysis. Their selection rules may then not be conveyed to the researcher who blithely assumes that their request had been fully honored. Fornell, C., & Larcker, D. F. (1981). IEEE Transactions on Software Engineering, 42(2), 120-135. Are these adjustments more or less accurate than the original figures? This step concerns the, The variables that are chosen as operationalizations must also guarantee that data can be collected from the selected empirical referents accurately (i.e., consistently and precisely). Assessing Unidimensionality Through LISREL: An Explanation and an Example. Finally, there is a perennial debate in QtPR about null hypothesis significance testing (Branch, 2014; Cohen, 1994; Pernet, 2016; Schwab et al., 2011; Szucs & Ioannidis, 2017; Wasserstein & Lazar, 2016; Wasserstein et al., 2019). Written for communication students, Quantitative Research in Communication provides practical, user-friendly coverage of how to use statistics, how to interpret SPSS printouts, how to write results, and how to assess whether the assumptions of various procedures have been met . PERSPECTIVEResearchers Should Make Thoughtful Assessments Instead of Null-Hypothesis Significance Tests. 3. 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. E. Quantitative Research in Educational and Psychology > Many educational. Other researchers might feel that you did not draw well from all of the possible measures of the User Information Satisfaction construct. Aspects of Scientific Explanation and other Essays in the Philosophy of Science. This debate focuses on the existence, and mitigation, of problematic practices in the interpretation and use of statistics that involve the well-known p-value. 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). 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. Some concerns of using ICT are also included in this paper which encompasses: a) High learning curve, b) Revised expectation on researcher, c) Research by the convenient of big data, and d) Decrease of social skills of researcher. 0. Sage. Streiner, D. L. (2003). Centefelli, R. T., & Bassellier, G. (2009). This logic is, evidently, flawed. 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). MacKenzie et al. The Nature of Theory in Information Systems. ), Measurement Errors in Surveys (pp. Intervening variables simply are not possible and no human subject is required (Jenkins, 1985). Psychometrika, 16(3), 291-334. 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. 2016). 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. These debates, amongst others, also produce several updates to available guidelines for their application (e.g., Henseler et al., 2014; Henseler et al., 2015; Rnkk & Cho, 2022). F. Quantitative Research and Social Science > the method employed in this type of quantitative social research are mostly typically the survey and the experiment.

Field studies are non-experimental inquiries occurring in natural systems. ), Research in Information Systems: A Handbook for Research Supervisors and Their Students (pp. If there are clear similarities, then the instrument items can be assumed to be reasonable, at least in terms of their nomological validity. Knowledge is acquired through both deduction and induction. Finally, there is debate about the future of hypothesis testing (Branch, 2014; Cohen, 1994; Pernet, 2016; Schwab et al., 2011; Szucs & Ioannidis, 2017; Wasserstein & Lazar, 2016; Wasserstein et al., 2019). The Discovery of Grounded Theory: Strategies for Qualitative Research. (2009). Mohajeri, K., Mesgari, M., & Lee, A. S. (2020). This is why often in QtPR researchers often look to replace observations made by the researcher or other subjects with other, presumably more objective data such as publicly verified performance metrics rather than subjectively experienced performance. Case Study Research: Design and Methods (4th ed.). On the other hand, field experiments typically achieve much higher levels of ecological validity whilst also ensuring high levels of internal validity. The American Statistician, 59(2), 121-126. 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. Figure 9 shows how to prioritize the assessment of measurement during data analysis. 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. The Measurement of End-User Computing Satisfaction. The term research instrument is neutral and does not imply a methodology.

Lauren Slater provides some wonderful examples in her book about experiments in psychology (Slater, 2005). Discovering Statistics using IBM SPSS Statistics. However, this is a happenstance of the statistical formulas being used and not a useful interpretation in its own right. University of Chicago Press. Because of its focus on quantities that are collected to measure the state of variable(s) in real-world domains, QtPR depends heavily on exact measurement. Tabachnick, B. G., & Fidell, L. S. (2001). Typically, QtPR starts with developing a theory that offers a hopefully insightful and novel conceptualization of some important real-world phenomena. Allyn & Bacon. Quantitative research is focused specifically on numerical information. The use of ICTs by nurses can impact their practice, modifying the ways in which they plan, provide, document, and review clinical care. It does not imply that certain types of data (e.g., numerical data) is reserved for only one of the traditions. 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. A seminal book on experimental research has been written by William Shadish, Thomas Cook, and Donald Campbell (Shadish et al., 2001). Researchers can conduct small-scale studies to learn more about topics related to instruction or larger-scale ones to gain insight into school systems and investigate how to improve student outcomes. It can include also cross-correlations with other covariates. The first cornerstone is an emphasis on quantitative data. Research in Information Systems: An Empirical Study of Diversity in the Discipline and Its Journals. A Type II error occurs when a researcher infers that there is no effect in the tested sample (i.e., the inference that the test statistic differs statistically significantly from the threshold), when, in fact, such an effect would have been found in the population. There are many other types of quantitative research that we only gloss over here, and there are many alternative ways to analyze quantitative data beyond the approaches discussed here. We can know things statistically, but not deterministically. Communication - How ICT has changed the way the researcher communicate with other parties. One common construct in the category of environmental factors, for instance, is market uncertainty. QtPR scholars sometime wonder why the thresholds for protection against Type I and Type II errors are so divergent. This step concerns the. A procedure for the analysis of LInear Structural RELations among one or more sets of variables and variates. The other end of the uncertainty continuum can be envisioned as a turbulent marketplace where risk was high and economic conditions were volatile. 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). Designing Surveys: A Guide to Decisions and Procedures. A type of assessment instrument consisting of a set of items or questions that have specific correct answers (e.g., how much is 2 + 2? Reinhart, A. Other techniques include OLS fixed effects and random effects models (Mertens et al., 2017). Theory & Psychology, 5(1), 75-98. In fact, Cook and Campbell (1979) make the point repeatedly that QtPR will always fall short of the mark of perfect representation. Predictive validity (Cronbach & Meehl, 1955) assesses the extent to which a measure successfully predicts a future outcome that is theoretically expected and practically meaningful. An alternative to Cronbach alpha that does not assume tau-equivalence is the omega test (Hayes and Coutts, 2020). The world is experiencing a digital revolution and the Philippines have the opportunity to play an enormous role in it. Coombs, C. H. (1976). European Journal of Epidemiology, 31(4), 337-350. 79-102). Miller, I., & Miller, M. (2012). (1988). Cengage Learning. Quantitative research can justify findings in Social research, though requirements could be verified/validated it could not deliver output expected for engineering. 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. Often, this stage is carried out through pre- or pilot-tests of the measurements, with a sample that is representative of the target research population or else another panel of experts to generate the data needed. We have co-authored a set of updated guidelines for quantitative researchers for dealing with these issues (Mertens & Recker, 2020). In addition to situations where the above advantages apply, quantitative research is helpful when you collect data from a large group of diverse respondents. All data are examined ex-post-facto by the researcher (Jenkins, 1985). Surveys have historically been the dominant technique for data collection in information systems (Mazaheri et al. Bayesian Data Analysis (3rd ed.). The data for this quantitative research were analyzed for both descriptive and inferential statistic using SPSS (version 21) software. Internal validity is a matter of causality. Sen, A., Smith, G., & Van Note, C. (2022). When we compare two means(or in other tests standard deviations or ratios etc. Wiley. Increasing the pace of globalization, this trend opened new opportunities not only for developed nations but also for improving ones as the costs of ICT technologies decrease. 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. ) Software the thresholds for protection against Type I and Type II errors are so divergent explain...
