What is the mean absolute deviation for 9, 7, 6, 8, 7, and 5?
a: 1
b: 2
c: 6
d: 7

1

Step-by-step explanation:

Here are the steps

1 Find the mean of the data set

2 Subtract the mean from each value ( ignore the minus signs ), that is the distance of each value from the mean

3. Find the mean of 2

mean = = = 7

value   distance

  9       | 9 - 7 | = 2

   7      | 7 - 7  | = 0

   6      | 6 - 7 | = 1

   8      | 8 - 7 | = 1

   7      | 7 - 7 | = 0

   5      | 5 - 7 | = 2

Find the mean of these values

mean absolute deviation = = 1
