Lie detector tests involve recording galvanic skin responses (minute amounts of persperation on the finger tips) as a person answers questions. Almosteveryone’s response increases (more sweat) when stressed or when lying. Examiners ask a series of factual questions (name, city born in, today’s date, etc.) and compare the skin response with “critical” information questions, such as “Where were you last on Tuesday between 9-11pm?” Suppose a test taker scored a 58.40, and the mean for this test is 46.40 with a SD of 3.00. Past studies have shown that liars tend to score 2 or more standard deviations away from the mean. Determine whether this taker is likely to be lying.
