Please explain what you mean by multiple times.
What is the medium in which the stimuli were shown?

Were they shown different angry faces? 

Where there subsets such as males/females? Adults/children? in the stimuli? In the respondents?

How did you validate the stimuli  were angry faces?

Were respondents shown multiple faces?  Did all respondents see the same stimuli? In the same order?

Were empathy scores assessed at one time per respondent?

Did respondents choose one and only one of the 4 response values? Or were they "check all that apply"

In psychology using a median split if often called "committing the invidious median split", there may be a way to use all of the information in the empathy measure.

How many respondents did you have?

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
