t-test: Paired samples

How to perform a paired samples t-test in jamovi:

1. You need two continuous variables, with each row representing a subject. i.e. the pair of values taken from each row represent paired measurements.
   A correct setup should look similar to this:

   

   
   
2. Select Analyses → T-Tests → Paired Samples T-Test.

   

   
   
3. Drag and drop your two variables to Paired Variables (You can drag these one at a time, or select both variables in a pair by holding down the Ctrl key while clicking on each, before dragging them across).

   

   
   
4. The result is shown in the right panel.
