Question

Thirty-four college students were asked how much money they spent on textbooks for the current semester. Their responses are shown in the following stemplot.

Describe a procedure for identifying potential outliers, and use the procedure to decide whether there are outliers among the responses for the money spent on textbooks.
Based on the stemplot, write a few sentences describing the distribution of money spent on textbooks for the 34 students.
One of the students spent $160 on books for the semester. If that value had been $260 instead, what effect would that increase have on the following statistics? Justify your answers.

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.
