The p-value usually represents the probability that you would get your results if the null hypothesis (in this case, that the samples are drawn from the same underlying distribution) were true,. You reject the hypothesis if the p-value is less than your predefined notion of a significant difference.

# Kolmogorov–Smirnov test p-value

(Asked by: username_0 on 2022-07-10)

I carried out a 2 sample [Kolmogorov–Smirnov](https://en.wikipedia.org/wiki/Kolmogorov%E2%80%93Smirnov_test) or "KS" test. I got a p-value of 0.11. That means the probability of 2 samples being of the same population is 0.11. Is it correct to say that the probability of the same is 11%?
