WebApr 24, 2024 · 1. The sampling distribution gives us the p-value for a given test statistic. You can compute a t-statistic using the formula, but if you want to know how likely that result would be if the null hypothesis were true (i.e., you want a p-value), you need the sampling distribution of the t-statistic to tell you that. – Noah. WebIn statistics, the Kolmogorov–Smirnov test ( K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2 ), one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample K–S test).
