Bootstrapping for learning statistics



Collecting data, producing plots such as histograms and scatter plots, and calculating numerical statistics such as means, medians, and regression coefficients are relatively concrete operations. In contrast, ideas related to the random variability of those statistics—sampling distributions, standard error, confidence intervals, central limit theorems, hypothesis tests, P-values, and statistical significance—are relatively abstract, and more difficult for students to understand. Bootstrap methods and permutation tests take those concrete tools, that students are used to using with data, and apply them to sampling distributions. This promotes understanding. We demonstrate using two examples—one involving linear regression, the other comparing two sample means. We finish by discussing why the bootstrap works, and what to watch out for.
