Determine whether your findings are significant. This app provides quick answers for both averages (means) and percentages.

Enter means, standard deviations, and group sizes or enter percentages and group sizes to determine whether the difference is statistically significant.

Using standard z-test procedures for independent groups, findings are reported at two levels of statistical significance: alpha = .05 and alpha = .01.
