The method in Morey (2008) and Cousineau (2005) essentially normalizes the data to remove the between-subject variability and calculates the variance from this normalized data. # Use a consistent y Our tutorials cover different topics including statistics, data manipulation and visualization!

The normed means are calculated so that means of each between-subject group are the same. This can be done in a number of ways, as described on this page.
