Welcome!

This web site currently features a number of statistical test calculators that social science students (and others) might find useful.

These were originally developed in order to anlalyse the data accumulated at the Philosophy Experiments web site (partly just for the fun of it, and partly because SPSS and the like are cumbersome and prohibitively expensive).

The calculators are designed to be easy to use - normally requiring only that you input your data and press a button. We hope you find them useful.
