Identify and explain a source of bias in the study described. Then suggest how the bias might have been avoided.

A popular magazine ran a survey about a web site that provides driving directions. Readers could register their responses on the magazine's web site.
◦ The magazine is biased in favor of the web site because it receives funding from the company. An independent pollster should be hired to run the survey.
◦ Because the respondents are self-selected, they are likely to represent those who have strong feelings about the issue. A better sampling method such as the simple random sampling used by most polling companies is needed.
