Calculate power & sample size for one-sample, two-sample and k-sample experiments. Advanced power and sample size calculator online: calculate sample size for a single group, or for differences between two groups (more than two groups supported for binomial data).
The 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, H 0, when it is not correct. Power = 1- β.
