What is a bootstrap? Can it really be used to give introductory statistics students a first look at statistical inference to construct confidence intervals? This webinar will address these questions by giving an overview of the process of generating bootstrap samples, using them to construct confidence intervals, and discuss how these intuitive ideas allow students to get real experience with inference much earlier in the course. The same methods can be applied in lots of situations (e.g. find a CI for a standard deviation as easily as a mean) and provide a bridge to the more theoretical normal and t-based methods. Techniques will be illustrated with examples using StatKey, a freely available web app designed to give students easy access to simulation-based inference such as bootstrapping and randomization tests.
