Answer:

No answer provided yet.I would recommend using the McNemar Test. This test is just like a Chi-Square test, except it takes into account the fact that the data in each cell comes from the same participant, thus removing the variability between subjects for each of the 3 conditions you have. You can use the McNemar Test with the 3 categories you have (and more conditions as well), although you’ll then need to do a post-hoc comparison test, or examine the confidence intervals to identify which conditions are significant different. There is a good discussion here.
