I have two independent groups of animals (n=4 in each group) observed under two different conditions (A and B) at the same time of the day and equal time interval (12 hours). For each group, behavioral data were recorded, divided into 7 mutually exclusive categories of behaviour. As a result, we have a different number and frequency of categories of behavioral acts between two groups (Total: Group A - 795 behavioural acts, Group B - 867).

I just visualized the total frequency of the categories in each group and the relative frequency as a percentage, but I do not know which statistical method to use with this data to determine the significance of the difference in the frequencies of each behavioral category between group A and B.

Can you suggest one?
