On there are some homework assignments Ive given my class, with solutions, that might help you better understand what we talk about today. Also, these notes will be posted at http: //www.stat.ufl.edu/ ~ whitaker/sta3024/morning/ (because your class is in the morning). Douglas Whitaker (Statistics Department) STA 3024: Nonparametric Statistics 22 February 2012 2 / 16 Nonparametric Statistics Were going to talk a little bit about nonparametric statistics . These are a set of tools that are often used for dealing with small datasets or datasets that are otherwise messy. Were going to cover some nonparametric alternatives to t-tests that we already know, that is, were going to talk about ways of analyzing data when we cant use a t-test (because the assumptions are violated).
