I want to compare multiple proportions between two samples. There are 60 brands of toys (T1, T2, T3...T60). I would like to know if overall, the proportion of respondents who own each brand of toy is significantly different between the two samples. I believe I can use a chi-squared test here but over 40% of the expected value cell counts are less than 5. Infact, 18% are less than 1. I cannot pool the brand category because there is no meaningful way to do this. What are my alternatives here? I know only basic statistics, so a little more elaboration for more advanced suggestions would be helpful.
