What is the MAD of this data set?
2, 3, 5, 7, 8, 8, 9

(add up all the data set and divide it by 7, why 7?, because there are about 7 numbers in the data set or the listed numbers)

2 + 3 + 5 + 7 + 8 + 8 + 9 = 49  

                                          = 7

                                             7

(subtract the data set and 7)

7 - 2 = 5

7 - 3 = 4

7 - 5 = 2

7 - 7 = 0

7 - 8 = 1

7 - 8 = 1

7 - 9 = 2

(add the difference and divide it by 7 again)

5 + 4 + 2 + 0 + 1 + 1 + 2 = 15

                                          = 2.14

                                           7

final answer would be 2.14
