I am studying experimental design this morning.

I did some SAS coding and must write this up now. I need to study the SAS printout some more, but I did notice that I have unequal variances with two blocking variables in my latin square design. I am wondering if I can look at the trends in these blocks and perhaps chose a transformation that might correct the unequal variances. I also know there is a technique for finding an appropriate transform but I may just try guessing.
