I would like to compare two dichotomous variables:

1) pass/fail for a statistics test before statistics class (pre-test)

2) pass/fail for a statistics test after statistics class (post-test)

I only have data on pass/fail (so dichotomous and not able to retrieve interval measure; therefore not able to execute a dependent t-test)

As my fellow students filled in the test anonymously I am not able to pair/match results of the pre-test and post-test (so I am not able to execute a McNemar Test).

Does anyone know which statistical test would be appropriate?

I hope to hear from you!

Kind regards,

Paul
