Another type of random sample is called a bootstrap sample. (it comes from the expression “pulling yourself up by your own bootstraps.”) given a data set with n observations, a bootstrap sample, also of size n, is when you randomly sample from the data set with replacement. to do so, you keep choosing a random integer from 1 to n and include that item in the sample. the “with replacement” part means that you can sample the same item more than once. for example, if n = 4, the sampled items might be 1, 2, 2, and 4. using the data in the file accounts receivable. xlsx, illustrate a simple method for choosing bootstrap samples with the randbetween and vlookup functions.
