This package of computer programs provides statistical power estimates for a comprehensive range of commonly used inferential statistics. The package also has utilities for generating critical values for tests of statistical significance, sequences of random numbers, random sequences for assignment of participants to independent groups, and the generation of Latin squares. Finally, the package contains a program that allows one to conduct Monte Carlo simulations with single-factor, factorial, and mixed-model analyses of variance. The programs are suitable for research purposes and as a teaching tool for students enrolled in statistics and research methods courses.
