Features:

· based on R, so it’s (pretty) fast

· does chi-squared, log-likelihood, and Fisher exact tests

· not limited to 2-by-2 tables – any number of columns or rows

· table of expected values is available

· basic intro to sig testing in the guidance notes (mostly for UG students)

Below is a cluster-analysis tool:
