WebIn Fisher's test, only the P value (2-tail) which is known in SPSS as Exact Sig (2-sided) is relevant. So in your case, it is 0.429. P = 0.429 is not significant as it is greater than 0.05. WebTime complexity is O(N log N), same as quick sort. Space complexity is O(N). This is not as efficient as a Fischer Yates shuffle but, in my opinion, the code is significantly shorter and more functional. If you have a large array you should certainly use Fischer Yates. If you have a small array with a few hundred items, you might do this.
