Avg in load test

Hello everybody,
I am a newbie and I want to run a load test using soapui.

I know that Avg means the average response time for all the requests in a test. (right?)

So if I run test and I receive some errors (let say cnt=100 and err=19), then does this Avg number contain response time for error responses and OK responses together? Or soapui computes average response time for OK responses only?

Thank you so much for any clue about this question.

Best Regards,
Mariam
