R tutorial: Testing assumptions for parametric tests
In this post, written as an R-markdown file and posted on RPubs, I discuss the assumptions for the use of parametric tests in R.
Parametric tests such as the various t tests, analysis of variance (ANOVA), and correlations are only valid if certain assumptions are met. When these assumptions are not met, the use of these tests in your research may lead to false claims.
In the post I show you the most important assumptions and how to test for them using the R programming language.
