Maybe you should make another poll asking the general poll users this exact race question without having it connected to the commercial. It’s probably similar proportions. Besides, as of right now, 28 people skipped voting. Do you think every one of them is a poc? Or do you think the proportions are similar to the poll results?
That’s a problem in drawing data. Scientists use a control group (asking what everybody’s race is) before an experimental group (asking what people’s race is of the people who voted no). You’re assuming this poll accurately describes the proportions of people in this group. Does that make sense? I’m no instructor, so I don’t know if I explained that clearly
