Confidence interval for Mean

The confidence interval for Mean option in the Descriptives, under mean Dispersion produces what I think are population (z) confidence intervals, is this the intended outcome? The proper sample confidence interval we can get through the one sample t module, but this seems like an oversight of something great to add to descriptives

I agree that the proper confidence interval to include in Descriptives is a t-based confidence interval, not the z-based interval that is currently used. This, of course, becomes much more of an issue with small sample sizes, but I see no reason not to use the t-based interval in all cases.

Either way it should be better labeled as such. Students regularly use it by accident
