Question

Data on weekday exercise time for 20 females, consistent with summary quantities given in the paper "An Ecological Momentary Assessment of the Physical Activity and Sedentary Behavior Patterns of University Students,"† are shown below.

Female—Weekday

10.0	90.6	48.5	50.4	57.4	99.6	0.0	5.0	0.0	0.0
5.0	2.0	10.5	5.0	47.0	0.0	5.0	54.0	0.0	48.6

Calculate the values of the median and interquartile range.

median:

interquartile range:

Interpret the values of the median and interquartile range.

The median exercise time of indicates that half of the exercise times were below , and the remaining half were above . The interquartile range tells us that the middle fifty percent of exercise times had a range of .

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.
