Each person in a large sample of German adolescents was asked to indicate which of 50 popular movies they had seen in the past year.

Each person was then classified into one of four groups Attitudibased on the amount of movie alcohol exposure (groups 1, 2, 3, and 4, with 1 being the lowest exposure and 4 being the highest exposure). Each person was also classified according to school performance. The resulting data is given in the accompanying table (from €œLongitudinal Study of Exposure to Entertainment Media and Alcohol Use among German Adolescents,€ Pediatrics [2009]: 989€“995).
