What analysis are you seeing the problem on?

Confidence interval for mean

What OS are you seeing the problem on?

Windows 11

Bug Description

This is happening with all data sets, so I am going to illustrate with a dataset I created: 1,2,3,4, ..., 13,14, 15. As you can see below, all confidence intervals reported using the method "T model" are exactly the same! image image image

While I have illustrated 3 cases, actually the confidence interval does not change at all!

Expected Behaviour

Confidence interval should change with confidence level. Here is the R output: x = c(1:15) image image

So, JASP is always reporting the 95% CI!

Steps to Reproduce

  1. Create new data entering values 1, 2, 3, ...., 15 in a column.

  2. image

  3. Choose column 1 as data. 4.Descriptives>Statistics>Confidence interval for mean

  4. Change Width options. image
