I have some problems with statistics in my experiment. I have to compare two samples, with 60 and 240 wing measures of flies, respectively. I used t- test for size difference between this two samples, but I am not sure if I can apply that statistics for some other data. I used some indices which estimated differences between left-L and right-R sides within each sample ( mean |R-L| ) and variance (R-L)-for this I used F test. I am not sure, although I know that this tests works with unequal samples, that I had correctly choice. Are there some more accurate tests, or modifications of these, because it is very important for me to find differences, if they really exist, of course.
