Hello,
I am wondering what statistics I should be using to analyse the following data:

2 groups (control and experimental).
Uneven group numbers (7 control subjects and 8 experimental subjects).
12 trials per day, with dependent variable of accuracy (response of either correct or incorrect).

I want to see if there is a difference in accuracy between my control and experimental groups on the first day overall, as well as on each individual trial of that day.

I have started off by coding a correct response as 1 and incorrect response as 0.

Is this the way to go? If so, where do I go from here? What is the name of the statistic I will need to use? :confused:

Thanks for any help. It will be much appreciated.
