Repeated measures although most commonly over time can be over other factors. left right arms, eyes, ears, etc. Members of a dyad is others might be spouses, parent-child, principal-teacher, etc. In other instances although levels of a factor may also be
given a different times the construct is not time per se. Consider
a study where I test learning. I could have two crossed repeated measures:
ambient noise and level of lighting. Each subject would be tested under each each possible combination of levels of these two factors. The order in which treatments were applied could even be counterbalanced so that time order was different for different groups of subjects.

Hi,.
If one observes two variables at the same subjects at the same time,
it still is repeated measure design, am I right? The observations are
of course correlated, and that time of observation is the same makes
no difference. The perfect example is when one compares length on left
and right arns of people from two populations. If both arms are
measured for each person from a sample, a population will be a factor
and an arm (left/right) should be treated as the repeated-measure
factor, or however we would call it.
Am I right?
Thanks ion advance,
