How good is the evidence? Evaluate each of these practice passages by examining the quality of the evidence provided. Passage Are children of alcoholics more likely to be alcoholics themselves? In answering the question, researchers sampled 451 people in Alcoholics Anonymous to see how many would say that one, or both, of their parents were alcoholics. People in AA used in the study currendy attend AA somewhere in Ohio, Michigan, or Indiana and were asked by people in charge of the local AA programs to volunteer to fill out a survey. The research found that 77 percent of the respondents had at least one parent they classified as an alcoholic. The study also surveyed 451 people randomly from the same states who claim not to be heavy drinkers. Of the nonheavy drinkers, 23 percent would label at least one of their parents as alcoholic.
