The first, and perhaps most notable, is that almost all trace of the skewness of the original samples has gone—the distributions of the estimates based on the resampled data are almost symmetric around the mean of the original data. This is a first glimpse of what is known as the Central Limit Theorem, which says that the distribution of sample means tends towards the form of a normal distribution with increasing sample size, almost regardless of the shape of the original data distribution.
