Lesson 3 homework practice mean absolute deviation

Assuming that am supposed to calculate the the mean absolute deviation of

1,2,3,4,5,6,7

mean absolute deviation is calculated by first calculating the mean;

(1+2+3+4+5+6+7) = 28/7

= 4

Then, find the absolute value (the difference between each value in the data and the mean) (x-μ)

= - 3,-2,-1,0,1,2,3

Absolute values = 3,2,1,0,1,2,3

Then we find the mean of the values,

3+2+1+0+1+2+3 = 12

= 12/7

= 1.7143

Therefore, the mean is 4, and the Mean absolute deviation is 1.7143
