Dear all

 

I want to correlate 2 variables (EEG and Motorperformance) for 18 observations. However, these variables consist of only 6 subjects that were measured 3 times (leading to 18 observations). How can I calculate the correlation coefficient and p-value and control for this "repeated observations" in the pooled dataset (I don't want to take the mean for each subject)?

 

All the best

Caroline
