Mean = 101
Mode = 102
Median = 102
Range = 20
MEAN: Add up all the numbers, then divide by how many numbers there are.
102 + 107 + 99 + 102 + 111 + 95 + 91 = 707
707 ÷ 7 = 101
MODE: Arrange all numbers in order from lowest to highest or highest to lowest and then count how many times each number appears in the set. The one that appears the most is the mode.
91,95,99,102,102,107,111
MEDIAN: Arrange the numbers from smallest to largest. If the amount of numbers is odd, the median is the middle number. If it is even, the median is the average of the two middle numbers in the list.
91,95,99,102,102,107,111
RANGE: Subtract the lowest number from the highest number
111 - 91 = 20
