Question

what are the adavantages of running a repeated measures anova as opposed to a one way anova?

Answer 1

Here are the some advantages of running a repeated measures anova as opposed to a one way anova:-

More statistical power: Repeated measures designs can be very powerful because they control for factors that cause variability between subjects.

Fewer subjects: Thanks to the greater statistical power, a repeated measures design can use fewer subjects to detect a desired effect size.

Quicker and cheaper: Fewer subjects need to be recruited, trained, and compensated to complete an entire experiment.

Assess an effect over time: Repeated measures designs can track an effect overtime, such as the learning curve for a task. In this situation, it’s often better to measure the same subject at multiple times rather than different subjects at one point in time for each.
