)the following data show the height, in inches, of 11 different plants in a garden: 9 4 10 9 5 2 22 10 3 3 5 after removing the outlier, what does the mean absolute deviation of this data set represent? on average, the height of a plant varies 2.8 inches from the mean of 6 inches. on average, the height of a plant varies 3.2 inches from the mean of 5 inches. on average, the height of a plant varies 2.8 inches from the mean of 5 inches. on average, the height of a plant varies 3.2 inches from the mean of 6 inches.

Ur outlier is 22so we will remove it.

now we find the mean (average) of the data set...
(9+4+10+9+5+2+10+3+3+5) / 10 = 60/10 = 6...this is ur mean

now we subtract the mean from every data value...and find its absolute value
9 - 6 = 3| 3| = 3
4 - 6 = -2...|-2| = 2
10 - 6 = 4..|4| = 4
9 - 6 = 3|3| = 3
5 - 6 = -1..|-1| = 1
2 - 6 = -4...|-4| = 4
10 - 6 = 4..|4| = 4
3 - 6 = -3...|-3| = 3
3 - 6 = -3...|-3| = 3
5 - 6 = -1...|-1| = 1

now we find the mean (average) of these numbers...that is ur MAD
(3+2+4+3+1+4+4+3+3+1) / 10 = 28/10 = 2.8

ur answer : on average, the height of the plant varies 2.8 inches from the mean of 6 inches
