WebAs Stijn pointed out, the k-s test returns a D statistic and a p-value corresponding to the D statistic. The D statistic is the absolute max distance (supremum) between the CDFs of the two samples. The closer this number is to 0 the more likely it is that the two samples were drawn from the same distribution.

WebApr 11, 2024 · However, since the p-value is just a value, we need to compare it with the critical value (⍺): p_value > ⍺ (Critical value): Fail to reject the null hypothesis of the statistical test. p_value ≤ ⍺ (Critical value): Reject the null hypothesis of the statistical test. The critical value that most statisticians choose is ⍺ = 0.05. WebWhen instructor calculated standard deviation (std) he used formula for unbiased std containing n-1 in denominator. If you have the whole data (or almost the whole) there are also another way how to calculate correlation. In this case you must use biased std which has n in denominator. And in overall formula you must divide by n but not by n-1.
