The mean is 14, the median is 13.5, the range is 8, and the midrange is 15.
Step-by-step explanation:
To calculate the mean, add up all the numbers and divide by the total number of games. In this case, the sum is 112 and there are 8 games, so the mean is 112/8 = 14.
To find the median, arrange the numbers in order from least to greatest and find the middle value. In this case, the middle values are 11 and 15, so the median is (11 + 15)/2 = 13.5.
The range is the difference between the greatest and least values. In this case, the range is 19 - 11 = 8.
The midrange is the average of the greatest and least values. In this case, the midrange is (19 + 11)/2 = 15.
