This article should serve as a useful guide for MIS researcher sin the planning, execution, and interpretation of inferential statistical analyses.Abstract:
Statistical power is a topic of importance to any researcher using statistical inference testing. Studies with low levels of statistical power usually result in inconclusive findings, even though the researcher may have expended much time and effort gathering the data for analysis. A survey of the statistical power of articles employing statistical inference testing published in leading MIS journals shows that their statistical power is, on average, substantially below accepted norms. The consequence of this low power is that MIS researchers typically have a 40 percent chance of not detecting the phenomenon under study, even though it, in fact, may exist.Fortunately, there are several techniques, beyond expanding the sample size (which often may be impossible) that researchers can use to improve the power of their studies. Some are as easy as using a different but more powerful statistical test, while others require developing more elaborate sampling plans or a more careful construction of the research design. Attention tot he statistical power of a study is one key ingredient in assuring the success of the study. This article should serve as a useful guide for MIS researcher sin the planning, execution, and interpretation of inferential statistical analyses.read more

Issues and opinion on structural equation modeling
TL;DR: In the past few years, the IS field has seen a substantial increase in the number of submissions and publications using structural equation modeling techniques, which has led some to describe this approach as an example of “a second generation of multivariate analysis”.

Using PLS path modeling for assessing hierarchial construct models: guidelines and impirical illustration
TL;DR: The authors provide guidelines outlining four key steps to construct a hierarchical construct model using PLS path modeling using a reflective, fourth-order latent variable model of online experiential value in the context of online book and CD retailing.
Journal ArticleDOI
Validating instruments in MIS research
TL;DR: An operating paradigm for renewal along dimensions previously unstressed is offered and it is argued that confirmatory empirical findings will be strengthened when instrument validation precedes both internal and statistical conclusion validity and that, in many situations, MIS researchers need to validate their research instruments.

The essential guide to effect sizes : statistical power, meta-analysis, and the interpretation of research results
TL;DR: This book discusses effect sizes, meta-Analysis, and the interpretation of results in the context of meta-analysis, which addresses the role of sample sizes in the analysis of power research.
Journal ArticleDOI
Building operations management theory through case and field research
TL;DR: This paper documents the advantages and rigor of case/field research and argues that these methods are preferred to the more traditional rationalist methods of optimization, simulation, and statistical modeling for building new operations management theories.

Belief in the law of small numbers
Amos Tversky,Daniel Kahneman +1 more
TL;DR: This paper reported that people regard a sample randomly drawn from a population as highly representative, i.e., similar to the population in all essential characteristics, and that the prevalence of the belief and its unfortunate consequences for psychological research are illustrated by the responses of 84 professional psychologists to a questionnaire concerning research decisions.
