Fisher-Yates shuffle algorithm for randomization …

The Fisher–Yates shuffle is an algorithm for generating a random permutation of a finite sequence—in plain terms, the algorithm shuffles the sequence. The algorithm effectively puts all the elements into a hat; it continually determines the next element by randomly drawing an element from the hat until no elements remain. The algorithm produces an unbiased permutation: every per… WebThe Fisher exact test is used as a replacement for the chi-square test when the expected frequency of one or more cells is less than 5.
