To assess the effect that chocolate may have on attitude, a researcher recruits a group of participants to complete the Acme Attitude Survey (AAS), which renders a 0 to 100 score (0 = very bad attitude . . . 100 = very good attitude). After giving the pretest, the researcher gives each participant a large bar of chocolate. Five minutes after the participant eats the chocolate, the researcher readministers the AAS.
