Question

Suppose the timing device used in the men’s race failed to activate at the start of the race and
instead began to record the times x seconds into the race.
• Consider how the competitors’ times would be affected.
• Would the x seconds be added to or subtracted from the times recorded to find the true
times? Would the median you calculated in question #1 be affected? If yes, how? If no,
why not?

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.
