Question

Shortly before a 1992 mayoral election, a local radio station conducted a Internet survey of voters. Based on the results of the survey, the radio station predicted that the Democratic candidate would beat the Republican candidate by a landslide. In fact, exactly the opposite happened. The trouble with the survey was that the radio station was largely liberal, and few Republicans visited its Web site. This is a classic example of an error in which phase of inferential statistics? A. Probability-based inference B. Data analysis C. Data organization D. Data gathering
