The mean, median, and mode of the data set. Round to the nearest tenth. 2, 10, 6, 9, 1, 15, 11, 10, 15, 13, 15 is mean = 9.7 , median = 10 , mode = 15 .

Mean = (1 + 2 + 6 + 9 + 10 + 10 + 11 + 13 + 15 + 15 + 15)/11 = 107/11 = 9.7

Median = 10

Mode = 15

Mean = (1 + 2 + 6 + 9 + 10 + 10 + 11 + 13 + 15 + 15 + 15)/11 = 107/11 = 9.7

Median = 10

Mode = 15
