Welcome to our course blog for Math 306, Introduction to Statistical Methods. During May Term (2013), students created posts to explain various statistical concepts and linked to websites containing useful information about statistical methods. By the end of the month, this blog became our own “textbook” using information already out there on the web. We hope this can serve as a resource for future stats students.
