I'm kind of new doing data mining, so sorry if my question is not very clear.
I'm working in a project that is aiming to do data mining over the interactions of the students with a e-learning platform. So, I'm trying to generate decision trees with some data that I collected (number of times that student use a resource, number of activities done, number quizzes taken, etc). The trees that I'm getting are interesting for me and according with the cross-validation tests, it's kind of accurate.
So my doubt is the following, I generated the tree with the data collected over two months and there were 44 students in the course. Is this enough data to trust in the tree? I have only the 44 instances that gather the two months of interactions...
Thanks in advanced for your help.
