WebUse the below form to enter your data for a Kolmogorov-Smirnov test. it is non-parametric and distribution free. Reject the null hypothesis of no difference between your datasets if Pis "small". In addition this page reports if your datasets seem to have normal or lognormal distribution. This may allow you to use other tests like the t-test. WebThe power calculator computes the test power based on the sample size and draw an accurate power analysis chart. Larger sample size increases the statistical power. The test power is the probability to reject the null assumption, H0, when it is not correct. Power = 1- β.
