is this sample of the audience members likely to be biased?
yes no

Explanation:

This sample is self-selected: only audience members who chose to speak participated, rather than a random cross-section of the full studio audience. People with strong, often negative, opinions are more likely to volunteer to share their views, so this sample does not represent the full audience's opinions.

yes
