ABSTRACT
The mean, median, and mode, the measures of central tendency, have important relationships with a histogram. Understanding these relationships helps to illuminate the basic contours of a distribution. The mode is the highest bar in a histogram. This chapter focuses on how the mean and median relate to the histogram. It provides the survey of mental health professionals employed by two community mental health agencies in rural northern and central Michigan. The survey sample included social workers (65.8"), psychologists (11"), counselors (8.2"), and other professionals (4"). The chapter demonstrates that community mental health professionals reported 0 to 16 hrs/week of family contact time. The mean of reported family contact hours per week was 3.5; the mean was 3.02 with two large outliers omitted. The average number of hours per week of family contact time for professionals who served children was 7.39; the average number of hours per week of family contact time for professionals who served adults was 2.58.
