What’s new

• Paired Comparison Test: when Binomial is selected, the second percentage is now easy to read. A lock icon and a short note show that the app fills it in for you.

• Paired Comparison Test: when Multinomial is selected and the two percentages add up to 100%, a hint suggests the Binomial test type.

• Difference of Two Means no longer shows degrees of freedom, to match our other STATS apps.
