12, 15, 11, 11, 7, 13 First, find the sum of the data. 12 + 15 +11 + 11 + 7 + 13 = 69 Then divide by the number of data. 69 / 6 = 11.5 The mean is 11.5 4. The mean is the average where the sum of all the numbers is divided by the total number of numbers, whereas the median is the middle value in the list of given numbers numerically ordered from smallest to biggest and mode is the value of the number which occurs most often in the list.
