Jacqui, Maybe you could try the Crochan Q test (it's a form of chi-square test). " Specifically, it tests whether several matched frequencies or proportions differ significantly among themselves." (from Statistica manual software). The test require dichotomized data. In your case, left/right for each anatomical part, as Fiona proposes. Maybe it helps Cheers Eduardo fiona beglane <[log in to unmask]> wrote: > Jacqui, >You could try the following, both of which I have used and are okay: > >Mike Fletcher and Gary R. Lock.
