  1. I have no idea what you would do at mekele university. The rest of the world might call this class or School Subject statistics, but I'm sure your university is unique in all the world so nobody else can help you. If you have a question about statistics, you might put that in the School Subject box so someone who is expert in that School Subject might see your post.
