I am not very confident with stats but am needing help with analysing my data.

I have observational data gained from observing marmosets over a period of five weeks. I am aiming to examine if there is any significant increase in time spent on certain behaviours over the course of these 5 weeks. I have two marmoset subjects. For each I have the total percentage of time spent on 8 different behaviours (stationary, grooming others, grooming self, playing, resting, locomotion, foraging natural and feeding on provisions) for each week (week 1,2,3,4,5). Am I correct in thinking that my independent variable is ‘percentage of time spent’ and my dependent variables is ‘week number’? Also Which test would be correct to use for this data?.

Any help would be greatly appreciated.

Thankyou.
