WebbB bootstrap samples and the find the standard deviation of these means. The more bootstrap replications we use, the more ‘replicable’ the result will be when a different set of samples is used. So if we re-ran the bootstrap analysis, we would be more likely to see the same results if we use a high number of bootstrap samples.

In 1878, Simon Newcomb took observations on the speed of light. The data set contains two outliers, which greatly influence the sample mean. (The sample mean need not be a consistent estimator for any population mean, because no mean needs to exist for a heavy-tailed distribution.) A well-defined and robust statistic for the central tendency is the sample median, which is consistent and median-unbiased for the population median.
