We tested 20 subjects from 2 species in an arena with two separate sides and recorded the number of transitions each individual made from one side to the other in both control (both sides light) and a treatment (light and a dark side) trials using a repeated measures design. Individuals typically made 1-4 transitions with 1 transition meaning that they moved to and stayed in the dark side. Which statistical test is appropriate to find out whether the number of individuals making 1 transition is significantly higher in the treatment than in the control trials? And to compare between species whether one tended to stay in the dark significantly more?
Hi,
Repeated measures in categorical variables are McNemar test and Cochran Q
test. Friedman's test is the non-parametric alternative to the one-way ANOVA with repeated measures.
There are excellent text books of ststs dealing with this topic.
