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

When a well-known sports writer wrote "Jocks Make Great Dads," he based conclusions about the general population of all men on 3,200 replies that he received after mailing 100,000 questionnaires to various country clubs.
◦ The sample is self-selected and the proportion of replies is small, so the responses are likely to have come from those with strong feeling about the issues. A better sampling procedure, such as interviews with 3,200 randomly chosen men, would have helped.
◦ The sample is random but the proportion of replies is small and all from men who play sports. A better sampling procedure, such as interviews with at least 10,000 randomly chosen men, would have helped.
