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.
Description
Shows the test being performed.
Proportion Difference
Shows the difference in the proportions between the levels of the X variable.
Lower 95%
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.
