Hi,
I have data from two studies that used different types of stimuli (sentence vs. word movies), but both types of stimuli have five different modalities (e.g., noisy vs. clear movie, etc.). The participants are different and with uneven numbers (20 vs. 15) in the two studies.
I would like to compare these two groups, so basically I have 3 factors:
Factor A: stimuli type has 2 levels:
1) sentence; 2) word
Factor B: stimuli modality has 5 levels:
Factor C: SUBJECTS (random effect, but I have uneven numbers here, 20 subjects for study1 and 15 for study2)
I am mostly interested in the interaction between Factor A * Factor B
Which AFNI function should I use for testing?
Thank you so much for helping!
