WebMar 5, 2015 · Chi-Square Test Example: We generated 1,000 random numbers for normal, double exponential, t with 3 degrees of freedom, and lognormal distributions. In all cases, a chi-square test with k = 32 bins was applied to test for normally distributed data. Because the normal distribution has two parameters, c = 2 + 1 = 3 The normal random numbers … WebMay 31, 2024 · The chi-square (Χ2) distribution table is a reference table that lists chi-square critical values.
