Fitting Models is Like Tetris: Crash Course Statistics #35

Today we’re going to wrap up our discussion of General Linear Models (or GLMs) by taking a closer look at two final common models: ANCOVA (Analysis of Covariance) and RMA (Repeated Measures ANOVA). We’ll show you how additional variables, known as covariates can be used to reduce error, and show you how to tell if there’s a difference between 2 or more groups or conditions. Between Regression, ANOVA, ANCOVA, and RMA you should have the tools necessary to better analyze both categorical and continuous data.
