Two Sample Test for Proportions

When both the X and Y variables have two levels, you can construct a confidence interval for the difference between the two proportions. It also computes the test corresponding to the confidence interval.

Note: See also Example of a Two Sample Test for Proportions.

Shows the lower endpoint of the confidence interval for the difference. Based on the adjusted Wald confidence interval.

Upper 95%

Shows the upper endpoint of the confidence interval for the difference. Based on the adjusted Wald confidence interval.

Adjusted Wald Test

Shows two-tailed and one-tailed tests.

Prob

Shows the p-values for the tests.
