The Gardener counted the numbers blooms on 10 flower bushes and then arrange the numbers from smallest to largest the numbers of moons on each bush 4,4,6,6,7,8,8,8,9 and 10. The mean pf these measurements is 7What is the mean absolute deviation? A) 1.2B)1.6C)2.0D) 12.0
Accepted Solution
A:
The formula of Mean Absolute Deviation is:
MAD = ∑|x- x̄| ---------- n
Where: x = data value x̄ = mean n = number of observations
You already have 2 values given which is the mean (7) and the number of observations (10). First you need to solve for the sum of x - x̄. Let's put that in a table to get a better picture:
