Today we're excited to announce a new free extension for SPSS Statistics: Stats Power. Stats Power calculates power and related statistics for a variety of tests including t-tests, proportion tests, ANOVA, correlation, chi-squared, and linear models. This free extension, based on R, recreates much of functionality previously found in SPSS SamplePower.
