Question

The National Football League (NFL) is an American sports league where 32 of the world's premier football teams compete against each other in a 16 game season. The frequency table shows the number of teams that finished the 2017 season with each possible number of wins.

Wins	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16
Frequency	0	0	2	2	2	1	3	4	2	4	3	4	5	0	0	0	0

What are the minimum, first quartile (?1), median, third quartile (?3), and maximum number of wins for the 32 teams in the 2017 season?

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.
