t-test: Paired samples

How to perform a paired samples t-test in jamovi:
  1. You need two continuous 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:

    data_format_ttest_paired


  2. Select AnalysesT-TestsPaired Samples T-Test.

    select_ttest_paired


  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).

    add_var_ttest_paired


  4. The result is shown in the right panel.

    output_ttest_paired


Tip

Those who have previous experience with SPSS may want to have a look at the side-by-side-comparison of how a t-test for paired samples is conducted in SPSS and jamovi.
