Question

Determine the first quartile, the median, the third quartile, the LOB, the UOB, the smallest data point greater than or equal to LOB, the largest data point less than or equal to UOB, and the set of outliers.

(b) Based on this information, draw a boxplot of the data. Make sure that your boxplot is at least 6 inches wide and that you include tick values on the horizontal axis.

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.
