Question

PLZ HELP ASAP IM ON THE TEST NOW Which sample is biased?

Answer 1

A. Interviews of random teens at a rock concert

These teens are all fans of the same music because they are attending the same concert. They cannot accurately represent all teens music choices because they are all bias toward the same music style. They are especially excited about it at the concert so responded are even more skewed.

Answer 2

I think (a) because they interviewed people who were already at a rock concert about what musician they enjoy the most
