Case managers in a therapeutic foster home agency completed assessments on at-risk youth who are clients of the agency. They assessed for risky behaviors as well as mental health needs. Higher scores indicate greater number of risky behaviors and greater need. Conduct the following analyses on their assessment scores for each subscale.

a. Construct a grouped frequency distribution with interval widths of 3 for both risky behaviors and mental health needs. Include frequencies, cumulative frequencies, percentages, and cumulative percentages. (Already Completed)

b. What percentage of youth scored 7 or higher on risky behaviors? What percentage of youth scored 6 or lower on mental health?

c. What is the mean and the median of both variables?

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
