One Way Repeated Measures ANOVA analyzes data where the same subjects undergo multiple conditions or time points. This test helps researchers determine whether significant differences exist in the means of the dependent variable across different conditions. What is One-Way Repeated Measures ANOVA? A One-Way Repeated Measures ANOVA extends the traditional ...

Setup library(tidyverse) # As always library(MASS) # Sampling from a multivariate distributions library(plotly) # For 3D plots OK, but what is AI actually about? Over the past two summers, I taught a statistics and research methods course to psychology students. Generally speaking, these students tend to be a little intimidated ...

Two-way repeated measures ANOVA is a powerful statistical test used to analyze datasets where two within-subject factors (independent variables) are measured multiple times for each subject. This test helps determine if there are significant differences between groups over time or across different conditions while accounting for individual variability. In this ...
