Reject the Null or Accept the Alternative? Semantics of Statistical Hypothesis Testing

If you are conducting a quantitative study for your dissertation, it is likely you have created a set of hypotheses to accompany your research questions. It is also likely that you have constructed your hypotheses in the “null/alternative” format. In this format, each research question has both a null hypothesis and an alternative hypothesis associated

The Chi-Square Test in Structural Equation Modeling

Anyone familiar with structural equation modeling (SEM) will know that there are a myriad of measures and indices that researchers may use to evaluate the fit of a model. Here, we will briefly highlight one particular assessment of model fit: the chi-square (χ2) test. The chi-square test is unique among possible the measures of fit

Testing Normality in Structural Equation Modeling

When conducting a structural equation model (SEM) or confirmatory factor analysis (CFA), it is often recommended to test for multivariate normality. Some popular SEM software packages (such as AMOS) assume your variables are continuous and produce the best results when your data are normally distributed. Here we discuss a few options for testing normality in

How to determine the appropriate sample size for structural equation modeling

Structural equation modeling (SEM) is an increasingly popular choice for quantitative statistical analyses, as it allows researchers to model complex relationships while taking into account measurement error of latent variables. Although there are great advantages to using SEM, the complexity of the analysis can be daunting, especially for students or beginning researchers. One of the
