I am collecting data on people's knowledge of radiation dosages before and after a teaching session. The data is NOT normally distributed. Therefore I will be comparing the MEDIAN of each set of data.

What statistical test should I use to compare the medians?

For the pre-teaching data set I have 17 responses.
I am anticipating 10-15 responses for the post-teaching data set.

Thanks

This might be a question more suited for the statistics stack exchange. A quick google search says maybe Mood's median test but im not too sure.
