  Hi Curious1,

  Here's a JASP file explaining the difference. Please let me know, whether it's clear.

  Cheers,
  Alexander

  Sorry about that, both varE and varF should only have the fifth case removed. I was a bit too enthusiastic removing cases and I can't remove files once they have been uploaded. Please only consider exampleMissingCorrect.jasp

  Hi Alexander,

  Thanks so much for helping me!

  exampleMissingCorrect.jasp well explains "Exclude pairwise". Back to my question, do you happen to know what "Exclude cases analysis by analysis" and "Exclude cases listwise" mean?

  Cheers!

  Hi Curious1,

  "Exclude cases analysis by analysis" is basically the equivalent of "exclude pairwise" and "exclude listwise" is the same as before. Here's the JASP file explaining what happens in the paired t-test (what you've seen before) and the independent t-test.

  Please let me know whether it's clear.

  Cheers,
  Alexander
