Use of this site constitutes acceptance of our terms and conditions of fair use. Statistics are tools of science, not an end unto themselves. It shows a histogram of the differences in means obtained by carrying out 1, in silico repeats of our experiment.

This is repeated until the evolved rules correctly attribute the texts.

Most but not quite all of the values will span a range of approximately four SDs.
