Created by David Howell of the University of Vermont, this lesson describes bootstrapping in the context of a statistics class for psychology students. Howell uses more than simple textual descriptions to illustrate the concept. Instead, the author takes screen shots from various different software programs to show how these theories work in a more practical way. The site is structured in such a way that the author first introduces the concept, then purpose, then examples and finally makes conclusions about the findings. Overall, this is a thoughtful and comprehensive overview of this statistical method.
