Do two data distributions differ?
What is Kolmogorov-Smirnov test (KS-test)?
- Ho- The two sample distributions are from the same population distribution
- H1- The two sample distributions are not from the same population distribution
Usually, KS-test is determined using software packages, and the corresponding p values determine whether the null hypothesis is rejected( both distributions are significantly different) or not. A low p-value( say less than 0.05) signifies that both the data distributions are significantly different.
