![]() ![]() ![]() In partial least squares (PLS) path modelling, this is referred to as multi-group comparison/analysis (often abbreviated as PLS-MGA). It became clear to me that I want to compare moderating effects through group comparison using study experience as a categorical variable, where group differences become apparent as differences in parameter estimates – as it is obviously the case in my studies. Particularly helpful was the article by Henseler and Fassott, which provides a good overview on this topic. mediationįirst of all, I asked myself whether I wanted to examine mediation or moderation or both at once. For this reason, I searched for methods to investigate differences between both studies. The results of the second study differed from the hypothesised causal relationship, that have been proven in the first study, and were in no accordance with expectations. A while ago, I conducted this survey with 35 graduate students. In this study, a survey was conducted with 133 first semester students to test a causal model based on the Decomposed Theory of Planned Behaviour (DTPB). Last year, I published a study about students’ intentions to use wikis in higher education. Finally, I show how I applied the non-parametric confidence set approach to compare two groups. This blog post is about the considerations I made while searching for a method to compare two studies that use the same causal model. ![]()
