importance of quantitative research in information and communication technology
In effect, researchers often need to make the assumption that the books, as audited, are accurate reflections of the firms financial health. A scientific theory, in contrast to psychoanalysis, is one that can be empirically falsified. R-squared is derived from the F statistic. The posterior can also be used for making predictions about future events. As this discussion already illustrates, it is important to realize that applying NHST is difficult. (1935). (Note that this is an entirely different concept from the term control used in an experiment where it means that one or more groups have not gotten an experimental treatment; to differentiate it from controls used to discount other explanations of the DV, we can call these experimental controls.) Statistical control variables are added to models to demonstrate that there is little-to-no explained variance associated with the designated statistical controls. Cluster analysis is an analytical technique for developing meaningful sub-groups of individuals or objects. Many great examples exist as templates that can guide the writing of QtPR papers. 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. A Comparison of Web and Mail Survey Response Rates. Hence interpreting the readings of a thermometer cannot be regarded as a pure observation but itself as an instantiation of theory. The same thing can be said about many econometric studies and other studies using archival data or digital trace data from an organization. Malignant Side Effects of Null-hypothesis Significance Testing. (2015). PLS-Graph users guide. This matrix is one of many methods that can be used to evaluate construct validity by demonstrating both convergent and discriminant validity. These are discussed in some detail by Mertens and Recker (2020). Research Methods in Social Relations (6th ed.). In theory-evaluating research, QtPR researchers typically use collected data to test the relationships between constructs by estimating model parameters with a view to maintain good fit of the theory to the collected data. (a) Research findings and their implications from 1960s to 1980s; (b) Research findings and their implications from1990s to 2000s, and future research. MacKenzie et al. Suppose you included satisfaction with the IS staff in your measurement of a construct called User Information Satisfaction but you forgot to include satisfaction with the system itself? MIS Quarterly, 30(3), 611-642. By chance, of course, there could be a preponderance of males or unhealthier persons in one group versus the other but in such rare cases researchers can regulate this in media res and adjust the sampling using a quota process (Trochim et al., 2016). (2012). 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. Written for communication students, Quantitative Research in Communication provides practical, user-friendly coverage of how to use statistics, 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). Why is the Hypothetico-Deductive (H-D) Method in Information Systems not an H-D Method? the Arts Council or ACE). 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. Does it mean that the firm exists or not? Moreover, experiments without strong theory tend to be ad hoc, possibly illogical, and meaningless because one essentially finds some mathematical connections between measures without being able to offer a justificatory mechanism for the connection (you cant tell me why you got these results). This distinction is important. Importance of quantitative research. We are ourselves IS researchers but this does not mean that the advice is not useful to researchers in other fields. This paper is the first to focus on the academic impact of quantitative research in social work developing measurable outcomes. Lauren Slater provides some wonderful examples in her book about experiments in psychology (Slater, 2005). There are several good illustrations in the literature to exemplify how this works (e.g., Doll & Torkzadeh, 1998; MacKenzie et al., 2011; Moore & Benbasat, 1991). 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). 2. For example, in Linear Regression the dependent variable Y may be the polynomial combination of aX1+bX2+e, where it is assumed that X1 and X2 each has a normal distribution. Most experimental and quasi-experimental studies use some form of between-groups analysis of variance such as ANOVA, repeated measures, or MANCOVA. Theory and Reality: An Introduction to the Philosophy of Science. A data analysis technique used to identify how a current observation is estimated by previous observations, or to predict future observations based on that pattern. MIS Quarterly, 36(1), iii-xiv. The most commonly used methodologies are experiments, surveys, content analysis, and meta-analysis. Dillon, A., & Gabbard, R. (1998). Research Methodology & Information and Communication Technology; NRB Preparation Guide for Assistant Director (Fourth Paper) Content With the caveat offered above that in scholarly praxis, null hypotheses are tested today only in certain disciplines, the underlying testing principles of NHST remain the dominant statistical approach in science today (Gigerenzer, 2004). Journal of the Academy of Marketing Science, 43(1), 115-135. Scandinavian Journal of Information Systems, 22(2), 3-30. A QtPR researcher may, for example, use archival data, gather structured questionnaires, code interviews and web posts, or collect transactional data from electronic systems. Secondary data also extend the time and space range, for example, collection of past data or data about foreign countries (Emory, 1980). It is important to note here that correlation does not imply causation. Sage. Regarding Type II errors, it is important that researchers be able to report a beta statistic, which is the probability that they are correct and free of a Type II error. The decision tree presented in Figure 8 provides a simplified guide for making the right choices. Gefen, D., & Larsen, K. R. T. (2017). 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. Psychological Bulletin, 52(4), 281-302. Appropriate measurement is, very simply, the most important thing that a quantitative researcher must do to ensure that the results of a study can be trusted. Epidemiology, 24(1), 69-72. John Wiley and Sons. A weighting that reflects the correlation between the original variables and derived factors. They involve manipulations in a real world setting of what the subjects experience. importance of quantitative research in arts and design. (1980), Causal Methods in Marketing. ER models are highly useful for normalizing data, but do not serve well for social science research models. Lawrence Erlbaum Associates. NHST logic is incomplete. When Null Hypothesis Significance Testing Is Unsuitable for Research: A Reassessment. But Communication Methods and Measures (14,1), 1-24. We felt that we needed to cite our own works as readily as others to give readers as much information as possible at their fingertips. This paper proposes a systematic and replicable method of patent analysis to identify problems to be solved requisite for sustainable technology planning and development, by implementing the concept of (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. From this standpoint, a Type I error occurs when a researcher finds a statistical effect in the tested sample, but, in the population, no such effect would have been found. In the classic Hawthorne experiments, for example, one group received better lighting than another group. 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. (1935). The resulting data is analyzed, typically through descriptive or inferential statistical techniques. Management Science, 29(5), 530-545. Lee, A. S., & Hubona, G. S. (2009). 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. Mertens, W., Pugliese, A., & Recker, J. Larsen, K. R. T., & Bong, C. H. (2016). Evidence suggests that teachers in rural secondary schools are still unclear about how to use technology appropriately to facilitate particular approaches The importance of quantitative research is that it allows establishing a relationship between variables through a structured method on a sample that is the Fornell, C., & Larcker, D. F. (1981). Im, G., & Straub, D. W. (2015). Nosek, B. Qualitative data goes beyond what quantitative data can do. Bailey, J. E., & Pearson, S. W. (1983). Without instrumentation validity, it is really not possible to assess internal validity. Too Big to Fail: Large Samples and the p-Value Problem. In other words, SEM allows researchers to examine the reliability and validity of their measurements as well as the hypotheses contained in their proposed theoretical model. MIS Quarterly, 25(1), 1-16. (1996). Moore, G. C., & Benbasat, I. Researchers using field studies typically do not manipulate independent variables or control the influence of confounding variables (Boudreau et al., 2001). In scientific, quantitative research, we have several ways to assess interrater reliability. Moreover, correlation analysis assumes a linear relationship. 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). It examines the covariance structures of the variables and variates included in the model under consideration. Wiley. (2020). The conceptual labeling of this construct is too broad to easily convey its meaning. The experimenter might use a random process to decide whether a given subject is in a treatment group or a control group. In research concerned with MIS Quarterly, 41(4), 1307-1333. A research instrument can be administered as part of several different research approaches, e.g., as part of an experiment, a web survey, or a semi-structured interview. and the many challenges in medical research and education. If readers are interested in the original version, they can refer to a book chapter (Straub et al., 2005) that contains much of the original material. A Primer on Partial Least Squares Structural Equation Modeling (PLS-SEM). The importance of quantitative systemic thinking in medicine Lancet. (2017). Sampling Techniques (3rd ed.). 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. They could, of course, err on the side of inclusion or exclusion. Springer. In a within-subjects design, the same subject would be exposed to all the experimental conditions. Information Systems Research, 24(4), 906-917. Chin, W. W. (2001). We can know things statistically, but not deterministically. Bollen, K. A. 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. This is the Falsification Principle and the core of positivism. Impact is measured through three indices: Google Scholar and Web of Science Citations, Moving to a World Beyond p < 0.05. The American Statistician, 73(sup1), 1-19. Emerging Varieties of Action Research: Introduction to the Special Issue. The most pertinent danger in experiments is a flaw in the design that makes it impossible to rule out rival hypotheses (potential alternative theories that contradict the suggested theory). Psychometrika, 16(3), 291-334. A second big problem is the inappropriate design of treatment and tasks. Scientific Research in Information Systems: A Beginners Guide (2nd ed.). They add value to goods and services, make business and government It incorporates techniques to demonstrate and assess the content validity of measures as well as their reliability and validity. Straub, D. W., Gefen, D., & Boudreau, M.-C. (2005). If multiple (e.g., repeated) measurements are taken, the reliable measures will all be very consistent in their values. Secondary data sources can be usually found quickly and cheaply. Shadish et al. Q-sorting offers a powerful, theoretically grounded, and quantitative tool for examining opinions and attitudes. Gasson, S. (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. Sources of data are of less concern in identifying an approach as being QtPR than the fact that numbers about empirical observations lie at the core of the scientific evidence assembled. The emphasis in sentences using the personal pronouns is on the researcher and not the research itself. Promoting an Open Research Culture. WebInformation and Communication Technology Research and its Impact on Growth and Job Creation underlining the importance of Community efforts in this area. But the effective labelling of the construct itself can go a long way toward making theoretical models more intuitively appealing. This form of validity is discussed in greater detail, including stats for assessing it, in Straub, Boudreau, and Gefen (2004). This means that survey instruments in this research approach are used when one does not principally seek to intervene in reality (as in experiments), but merely wishes to observe it (even though the administration of a survey itself is already an intervention). The purpose of survey research in exploration is to become more familiar with a phenomenon or topic of interest. This post-positivist epistemology regards the acquisition of knowledge as a process that is more than mere deduction. In I. Lakatos & A. Musgrave (Eds. Journal of the Association for Information Systems, 12(9), 632-661. While differences exist in some aspects, the general manner of interpretation is quite similar to linear regression (Hair et al., 2010). Methods: Quantitative, mixed-method, and qualitative reviews that aimed to evaluate the influence of four eHealth domains (eg, management, computerized decision Causality: Models, Reasoning, and Inference (2nd ed.). As a simple example, consider the scenario that your research is about individuals affections when working with information technology and the behavioral consequences of such affections. Following the MAP (Methods, Approaches, Perspectives) in Information Systems Research. Churchill Jr., G. A. Problems with construct validity occur in three major ways. Corder, G. W., & Foreman, D. I. 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). 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. 443-507). 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). Quantitative Data Analysis with SPSS 14, 15 & 16: A Guide for Social Scientists. Others require coding, recoding, or transformation of the original data gathered through the collection technique. However, critical judgment is important in this process because not all published measurement instruments have in fact been thoroughly developed or validated; moreover, standards and knowledge about measurement instrument development and assessment themselves evolve with time. 2004). Unfortunately, unbeknownst to you, the model you specify is wrong (in the sense that the model may omit common antecedents to both the independent and the dependent variables, or that it exhibits endogeneity concerns). This study is underpinned on and concurred with DeLone & McLean's (1992, 2003) Information Systems (IS) Success Model in which ICT had effects on productivity of social science researchers. You are hopeful that your model is accurate and that the statistical conclusions will show that the relationships you posit are true and important. Secondarily, it is concerned with any recorded data. There are numerous ways to assess construct validity (Straub, Boudreau, and Gefen, 2004; Gefen, Straub, and Boudreau, 2000; Straub, 1989). Assessing measure and measurement validity is the critical first step in QtPR. But many books exist on that topic (Bryman & Cramer, 2008; Field, 2013; Reinhart, 2015; Stevens, 2001; Tabachnick & Fidell, 2001), including one co-authored by one of us (Mertens et al., 2017). 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. Lets take the construct labelled originally Co-creation. Again, the label itself is confusing (albeit typical) in that it likely does not mean that one is co-creating something or not. Annual Review of Psychology, 60, 577-605. Human Relations, 46(2), 121-142. WebUnderstanding and addressing these challenges are important, independent from whether the research is about confirmation or exploration. Predictive validity (Cronbach & Meehl, 1955) assesses the extent to which a measure successfully predicts a future outcome that is expected and practically meaningful. The whole point is justifying what was done, not who did it. WebThis study investigates the role of information technology (IT) professional certifications in IT instructors' teaching quality in higher education institutions (HEIs) in Tanzania. Randomizing gender and health of participants, for example, should result in roughly equal splits between experimental groups so the likelihood of a systematic bias in the results from either of these variables is low. 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. MIS Quarterly, 12(2), 259-274. 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. Organizational Research Methods, 13(4), 668-689. (2013). It focuses on three leading British-based generic journals over a 10-year period, encapsulating 1490 original articles. Research Methods: The Essential Knowledge Base (2nd ed.). This task can be carried out through an analysis of the relevant literature or empirically by interviewing experts or conducting focus groups. Crossover Designs in Software Engineering Experiments: Benefits and Perils. Einsteins Theory of Relativity is a prime example, according to Popper, of a scientific theory. Watershed moments include Moshanskys 1992 Citation 7 analysis of the 1989 Dryden accident and Haddon-Caves 2009 Citation 8 analysis of the 2006 Nimrod loss. A clarifying phrase like Extent of Co-creation (as opposed to, say, duration of co-creation) helps interested readers in conceptualizing that there needs to be some kind of quantification of the amount but not length of co-creating taking place. Quantitative Research. Field studies are non-experimental inquiries occurring in natural systems. A positive correlation would indicate that job satisfaction increases when pay levels go up. Straub, Gefen, and Boudreau (2004) describe the ins and outs for assessing instrumentation validity. 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. Statistics Done Wrong: The Woefully Complete Guide. Philosophical Transactions of the Royal Society of London. Webimportance of quantitative research in information and communication technology. Misinterpretations of Significance: A Problem Students Share with Their Teachers? Frontiers in Psychology, 3(325), 1-11. Most likely, researchers will receive different answers from different persons (and perhaps even different answers from the same person if asked repeatedly). The term research instrument is neutral and does not imply a methodology. rather than discovery. Obtaining such a standard might be hard at times in experiments but even more so in other forms of QtPR research; however, researchers should at least acknowledge it as a limitation if they do not actually test it, by using, for example, a Kolmogorov-Smirnoff test of the normality of the data or an Anderson-Darling test (Corder & Foreman, 2014). North-Holland. Scale Development: Theory and Applications (5th ed.). Elsevier. There are three main steps in deduction (Levallet et al. Also known as a Joint Normal Distribution and as a Multivariate Normal Distribution, occurs when every polynomial combination of items itself has a Normal Distribution. 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. It aims to be objective. Typically, a researcher will decide for one (or multiple) data collection techniques while considering its overall appropriateness to their research, along with other practical factors, such as: desired and feasible sampling strategy, expected quality of the collected data, estimated costs, predicted nonresponse rates, expected level of measure errors, and length of the data collection period (Lyberg and Kasprzyk, 1991). Interpretation of Formative Measurement in Information Systems Research. Harcourt Brace College Publishers. PERSPECTIVEResearchers Should Make Thoughtful Assessments Instead of Null-Hypothesis Significance Tests. The number of such previous error terms determines the order of the moving average. As a caveat, note that many researchers prefer the use of personal pronouns in their writings to emphasize the fact that they are interpreting data through their own personal lenses and that conclusions may not be generalizable. The aim of spatial analysis is to understand differences across space rather than regularities. Research Methodologies and MIS Research. It is out of tradition and reverence to Mr. Pearson that it remains so. 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. 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. On the other hand, field experiments typically achieve much higher levels of ecological validity whilst also ensuring high levels of internal validity. Guo, W., Straub, D. W., & Zhang, P. (2014). Instrumentation in this sense is thus a collective term for all of the tools, procedures, and instruments that a researcher may use to gather data. This paper focuses on the linkage between ICT and output growth. Multivariate analysis of variance (MANOVA): Multivariate analysis of variance (MANOVA) is a statistical technique that can be used to simultaneously explore the relationship between several categorical independent variables (usually referred to as treatments) and two or more metric dependent variables.

You are hopeful that your model is accurate and that the statistical conclusions will show that the relationships you posit are true and important. Secondarily, it is concerned with any recorded data. There are numerous ways to assess construct validity (Straub, Boudreau, and Gefen, 2004; Gefen, Straub, and Boudreau, 2000; Straub, 1989). Assessing measure and measurement validity is the critical first step in QtPR. But many books exist on that topic (Bryman & Cramer, 2008; Field, 2013; Reinhart, 2015; Stevens, 2001; Tabachnick & Fidell, 2001), including one co-authored by one of us (Mertens et al., 2017). 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. Lets take the construct labelled originally Co-creation. Again, the label itself is confusing (albeit typical) in that it likely does not mean that one is co-creating something or not. Annual Review of Psychology, 60, 577-605. Human Relations, 46(2), 121-142. WebUnderstanding and addressing these challenges are important, independent from whether the research is about confirmation or exploration. Predictive validity (Cronbach & Meehl, 1955) assesses the extent to which a measure successfully predicts a future outcome that is expected and practically meaningful. The whole point is justifying what was done, not who did it. WebThis study investigates the role of information technology (IT) professional certifications in IT instructors' teaching quality in higher education institutions (HEIs) in Tanzania. Randomizing gender and health of participants, for example, should result in roughly equal splits between experimental groups so the likelihood of a systematic bias in the results from either of these variables is low. 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. MIS Quarterly, 12(2), 259-274. 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. Organizational Research Methods, 13(4), 668-689. (2013). It focuses on three leading British-based generic journals over a 10-year period, encapsulating 1490 original articles. Research Methods: The Essential Knowledge Base (2nd ed.). This task can be carried out through an analysis of the relevant literature or empirically by interviewing experts or conducting focus groups. Crossover Designs in Software Engineering Experiments: Benefits and Perils. Einsteins Theory of Relativity is a prime example, according to Popper, of a scientific theory. Watershed moments include Moshanskys 1992 Citation 7 analysis of the 1989 Dryden accident and Haddon-Caves 2009 Citation 8 analysis of the 2006 Nimrod loss. A clarifying phrase like Extent of Co-creation (as opposed to, say, duration of co-creation) helps interested readers in conceptualizing that there needs to be some kind of quantification of the amount but not length of co-creating taking place. Quantitative Research. Field studies are non-experimental inquiries occurring in natural systems. A positive correlation would indicate that job satisfaction increases when pay levels go up. Straub, Gefen, and Boudreau (2004) describe the ins and outs for assessing instrumentation validity. 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. Statistics Done Wrong: The Woefully Complete Guide. Philosophical Transactions of the Royal Society of London. Webimportance of quantitative research in information and communication technology. Misinterpretations of Significance: A Problem Students Share with Their Teachers? Frontiers in Psychology, 3(325), 1-11. Most likely, researchers will receive different answers from different persons (and perhaps even different answers from the same person if asked repeatedly). The term research instrument is neutral and does not imply a methodology. rather than discovery. Obtaining such a standard might be hard at times in experiments but even more so in other forms of QtPR research; however, researchers should at least acknowledge it as a limitation if they do not actually test it, by using, for example, a Kolmogorov-Smirnoff test of the normality of the data or an Anderson-Darling test (Corder & Foreman, 2014). North-Holland. Scale Development: Theory and Applications (5th ed.). Elsevier. There are three main steps in deduction (Levallet et al. Also known as a Joint Normal Distribution and as a Multivariate Normal Distribution, occurs when every polynomial combination of items itself has a Normal Distribution. 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. It aims to be objective. Typically, a researcher will decide for one (or multiple) data collection techniques while considering its overall appropriateness to their research, along with other practical factors, such as: desired and feasible sampling strategy, expected quality of the collected data, estimated costs, predicted nonresponse rates, expected level of measure errors, and length of the data collection period (Lyberg and Kasprzyk, 1991). Interpretation of Formative Measurement in Information Systems Research. Harcourt Brace College Publishers. PERSPECTIVEResearchers Should Make Thoughtful Assessments Instead of Null-Hypothesis Significance Tests. The number of such previous error terms determines the order of the moving average. As a caveat, note that many researchers prefer the use of personal pronouns in their writings to emphasize the fact that they are interpreting data through their own personal lenses and that conclusions may not be generalizable. The aim of spatial analysis is to understand differences across space rather than regularities. Research Methodologies and MIS Research. It is out of tradition and reverence to Mr. Pearson that it remains so. 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. 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. On the other hand, field experiments typically achieve much higher levels of ecological validity whilst also ensuring high levels of internal validity. Guo, W., Straub, D. W., & Zhang, P. (2014). Instrumentation in this sense is thus a collective term for all of the tools, procedures, and instruments that a researcher may use to gather data. This paper focuses on the linkage between ICT and output growth. Multivariate analysis of variance (MANOVA): Multivariate analysis of variance (MANOVA) is a statistical technique that can be used to simultaneously explore the relationship between several categorical independent variables (usually referred to as treatments) and two or more metric dependent variables.
