Hope it was helpful.

It's unclear what you t-tested here. Ideally, you would test for difference between groups of "Is there a difference in number of endorsements between people who got a "yes" in advancing to the next round or not". As a followup, is there a difference between those who's preferred was most endorsed or not?

I'm a bit stunned that you didn't recognize Language as programming language...... :(

As an example, people probably get endorsed for SQL or CSS far more than their programming language of choice that is tested in an interview.

What do you mean re not recognizing language as a programming language? We only counted actual programming languages, i.e. not SQL, HTML, CSS, etc.
