Quick Chi

The chi-squared test is one of the most important tests in statistics. It tests whether the observed frequencies in a distribution differ significantly from the frequencies which might be expected according to some 'assumed hypothesis'. QuickChi is a programme for carrying out chi-squared tests. Version 1.1 now allows calculation of chi squared analysis not only for 2x2 tables but also for more complicated data sets up to 2x5. A logical error in the calculation algorithm has been put right and some cosmetic bugs have also been fixed. QuickChi should run on any Mac and is freeware.
