Mean: 25Median: 19Mode: 19Range: 70Rewrite the values from least to greatest:10, 11, 15, 19, 19, 19, 25, 27, 80Mean is the average:(10 + 11 + 15 + 19 + 19 + 19 + 25 + 27 + 80)÷ 9 = 25Median is the middle value in the list:the 5thnumber = 19Mode is thenumber that is repeated more often:19 is repeated thrice so 19 is the mode.Range is the difference of the largest value and the smallest value: 80 - 10 = 70
(11 + 16 + 15) ÷ 3 = 14 is the average
