AcaStat Statistical Software — Designed by a statistics professor for students.

AcaStat is easy to use and includes a help module that explains how to run the statistical procedures and, for most analyses, annotated output is available to help student interpretation. A random sampling procedure can be used to test the central limit theorem. Example data files are available in a pull-down menu.

For purchased versions, AcaStat provides summary statistics modules that help students confirm hand calculations and experience the impact on statistical significance when changing effect size, variation, and sample size. There are graphic displays for confidence intervals and significance p-values.
