Adipose Industries uses a system whereby three different managers evaluate each employee. These evaluations determine whether the employee gets a pay raise or not and how much. Employee Peter is evaluated by managers Mark, Mary, and John. Mark gives Peter a high score on his evaluation. This score is within 3 points of the scores that Mark gave to the last 10 employees he rated. Mary gives Peter an average score. The last 10 employees Mary evaluated all got similarly average scores. John gives Peter a lower than average score. John previously evaluated 10 other employees, giving them all scores that were slightly below average. Which of the above managers is probably subject to a central tendency error (where the rater sees everyone as average)? A. Mark B. Mary C. John O D. Mark, Mary, and John
