1. ### Multi level modeling vs. Repeated Measures ANOVA interaction

I am examining perceived social support and coping in a group of approximately 40 participants (about 20 participants in two groups) who all recieved an intervention to address loss, with data collected at pre (T1), post (T2), one month post (T3), and three months post (T4). I also have...

3. ### Is a one-way repeated measures ANOVA appropriate?

I am investigating the ability to divide attention while driving and engaging in a secondary task. I am using a repeated measures design. Each participant must complete two tests. In test one there are traffic lights and sudden moving hazards, and in test two there are traffic lights and a lead...
4. ### Divergent results - RMANOVA vs. paired samples t-tests

Hi there, I'm analyzing a dataset (a pre - post intervention), where I have a baseline and 2 post-intervention time points. If I perform a RMANOVA (factor time (pre, p1, p2)), the resultant p value is above 0.05. However, if I perform a paired samples t-tests (2 comparisons, pre-p1 and...
5. ### Repeated Group Measurements, but Unpaired in that I can't Follow an Individual

I run an assay on the same two groups, a treatment group and a control group, everyday. I then want to run a statistical test to see if the two groups behave differently. I was planning to run a two way ANOVA with post-tests, but my problem is that the analysis clearly requires a "repeated...
6. ### simulating a repeated measures ANOVA with mixed linear model analysis

Hi all, I have a data set with two within subject variables, word category (2 levels) and time (3 levels), and I have a between subjects variable, namely group (2 levels). My dependent variable is reaction time (RT). If I run three separate repeated measures ANOVA for the three different...
7. ### how to do a contrast analysis for an interaction between two within subjects effects?

Hello! I have a quite simple data pattern but find it hard to test a specific contrast I expected. I have 2 within subjects factors, each with two levels. Let's call them reward (high vs. low) and task pressure (high vs. low), while the dependent variable is performance (see the example GLM...
