Introduction to Statistics

This 3 day crash course in Statistics is meant to teach the basic statistical principles: we want to use data for decision making. For that, we will make use of the freely available state-of-the-art software R.

You can work on the assignments as a group but you should submit the assignments individually. In fact, I highly encourage you to work together since everyone here has different programming experience. You can upload the assignments to this wiki or send to me by email to hofmann@iastateSPAMMAPS.edu.
