Question

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

Answer 1

(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

Answer 2

Answer:

do you mean the mode cause that would be 8 and the mean would be 6 and median would be 7 and the range would also be 7

the mad would be 2.2857 idk what your rounding to but i hope this helps
