I have been searching online for an appropriate way to analyse data obtained using a 4x4 latin-square design (and more specifically how to do this in R).
I have some sources online that say the data should be analysed using a repeated measures ANOVA. I have tried this, but want to make sure that I have entered the error term correctly or whether there is a better method.
The design is repeated-measures: I have my treatment factor (correction) with 4 levels, and another factor (narrative) which also have 4 levels. Correction and narrative have 4 different combinations or orders.
Any help at all would be much appreciated!
