If you have only two levels for your outcomes (e.g. angry, neutral) then logistic regression could be used.

Subject: Non-parametric test- which one to use?

Dear experts,

I am not sure which test I am supposed to use and was wondering whether
anyone could guide me.

DATA:

Subjects chose among 'angry', 'neutral', 'sad', 'happy', and 'fear' when
they were viewing angry faces (multiple times). Their empathy scores were
also assessed.

MY QUESTION:

I would like to see whether people with high empathy scores (divided by the
median score) and low empathy scores differed in the number of or the
proportion of their responses, 'anger' and 'neutral' for the angry faces.
For instance, if our hypothesis is correct, I would like to say that low
empathic people rate angry faces as 'neutral' more frequently than highly
empathic people...

Which test would you recommend that I use?

Thanks,
Claire
