Troubleshooting
Problem
I'm looking for the standard large sample normal theory confidence interval on a binomial proportion, and I don't see it in SPSS. Is it available?
Resolving The Problem
The "standard" large sample normal theory confidence intervals for binomial proportions are also known as Wald confidence intervals. They are available beginning in Version 27.0.1 in the PROPORTIONS procedure, which handles single proportions, as well as differences between two independent or paired proportions. See the menu items under Analyze>Compare Means and Proportions.
Wald confidence intervals for individual proportions are available, but are not shown by default, as there are other types of intervals with better coverage properties.
