Power on X is a Mac OS X native (cocoa) program for the calculation of statistical power. The program can perform calculations of required sample size to achieve a desired power, and calculations of power for previously run studies/experiments. In addition, the paid version can generate power/sample size tables.Requirements: Mac OS X 10.2, 10.3 or 10.4
