The bootstrap is a resampling method to estimate the sampling distribution of a statistic.

The bootstrap is a technique to estimate the sampling distribution of a statistic, based on resampling from a dataset, estimating the parameters from the re-sampled data, and comparing those estimates to the (known) values for the dataset itself. There are many variants of bootstrapping used in specialized analyses.
