I ran a within-subject study with the primary measure of interest being response time. Due to response time being right skewed I used Wilcoxon signed ranks test on the median values. I am having to revisit this work and I am now wondering/checking that using the Wilcoxon signed ranks test is feasible when working with response time.
The study was a within subject design with a single two level factor and the main measurement was reaction time. The total number of participants was 15
