repeated measures ANOVA

Repeated measures ANOVA is a statistical method used to compare the same group of people or items across multiple conditions or time points. For example, if you measure students’ test scores before, during, and after a training program, this analysis helps determine if the scores changed significantly over time. It accounts for the fact that measurements are related since they come from the same subjects, improving accuracy. Essentially, it helps to identify whether differences observed are likely due to the conditions or just random variation, providing a clear way to analyze data where repeated observations are made on the same entities.
