I am doing a psychology experiment in change blindness, my IV is the type of change, with 3 levels - congruent, incongruent and within-category. I am using all the same participants for all 16 trials, with a control trial of no change too. I am using a repeated measures ANOVA to analyse my data which has been given to me by the university where I am studying. I am confused as to whether reaction time is giving me the 'mean' scores for each type of change or whether it is from the percentage of changes detected. Is there a way to tell?
