I have a data set of observations that show an observed effect following education. I have a baseline position (taken prior to the education) which shows the number of students showing particular knowledge and then post-education an increased number of students showing particular knowledge. How do I show that the gain is significant? Unfortunately sample size is relatively small (60 students).
Also I have data on the genders of the students. Looking at the data I have I would say the impact of gender is not relevant but how do I show that is true?
