A television program asks it's viewers to visit a website to indicate their preferences for two presidential candidates. 76% of the viewers who responded preferred candidate A, so the television program announced that most people prefer candidate A. Is this biased or unbiased?

Respuesta :

This study is biased. This is because the people who responded did so voluntarily. Voluntary surveys are not always accurate. Also, the people who responded were only people who watched a specific TV program. This does not accurately represent the total population of likely voters.

I would say that this is biased because only certain people might watch that television program.
