just a quick question I was a little unsure about. Any thoughts much appreciated!
Say I am running an 2 condition experimental trial where one of the outcomes is a z-score (e.g. cognitive test measured pre and post each condition).
To make the results more 'meaningful', would it be Kosher/correct to calculate the % difference in the z-score between the 2 conditions? To show there was x % difference in the z-scores between the 2 conditions.
