I am currently trying to analyse an experiment to assess if rats with cerebral malformations have a sensitivity deficit on one of their front paws. I put 2 sticky dots on their front paws then look which side they turn to first. I repeated this over 4 trials.

So my data look like that (with "n" being the

**number of rats**contacting a dot on the left side first or on the right side first)

What I want to know is

**if the proportion of rats turning to the left side first is different in groups A and B**. In that case, could I pool all time points and perform a Fisher test or would this be incorrect?

I have tried performing 2-way ANOVA on Prism 6 but realized this was not appropriate as it would average both "left" and "right" subcolums.

If anyone knows how I could treat these data properly, it would be really helpful.

Thanks to everyone who will have taken time to read this
