: Hello everybody,
you havn't really given enough information but here is a suggestion. you
have three separate groups. If they are not the treatment groups with
random assignment, anything else you do will be VERY dubious. You could
use sex as a blocking factor and age as a covariate. What is the purpose
of the 120 observations? You could construct a SMALL number of relevant
variables from these observations and do a MANOVA, for example linear,
quadratic and cubic trends if you are simply interested in what happens
over time. You might also do a between groups analysis on the final time
or average time. It's hard to say without knowing the details.
What your REALLY should do is consult a statistician about the specifics.
