Question

Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth.

11, 9, 7, 6, 8, 2, 15, 1, 12, 15, 14

Answer 1

mean = add all the numbers up and divide by the number of numbers.
mode, most common number in the set (which number is repeated the most)
median, order them from least to greatest and cross out one by one from each side and see which ends up in the middle, if there are two, add those two up and divide by 2.

Answer 2

mean = 9.1, median = 9, mode = 15
