Regardless of the shape of the bootstrap sampling distribution, we can use the percentile method to construct a confidence interval. Using this method, the 95% confidence interval is the range of points that cover the middle 95% of bootstrap sampling distribution. The following examples use StatKey. This lesson corresponds to Chapter 3 in the Lock 5 textbook. In Lessons 2 and Lesson 3 you learned about descriptive statistics. Lesson 4 begins our coverage of inferential statistics which use data from a sample to make an inference about a population.
