WebI want to write a piece of code to test whether the numbers from it are truly uniformly distributed using chi-square test. I select r to be very big like 1,000,000, and I generate random integers 10,000,000 times. Then I get the X^2. The next thing I need to do is to check the chi-square value against a degree of freedom table.

WebNov 7, 2024 · What is the Critical Value of a 0.05 in Chi Square Test? The critical value of a 0.05 in chi square test is 3.84. This means that if the chi square statistic is less than or equal to 3.84, then the null hypothesis can be accepted. If the chi square statistic is greater than 3.84, then the null hypothesis must be rejected.
