On average, the height of a plant varies 3.2 inches from the mean of 6 inches.
<h3>What does the mean absolute deviation represent? </h3>
An outlier is a number that is way smaller or way larger than that of other numbers in a data set. The outlier is 22.
Mean absolute deviation = (1/n) x ∑ l x - m(x) l
Mean without the outlier : (9 + 4 + 10 + 9 + 5+ 2 + 10 + 3 + 3+ 5) / 10 = 6
(1/10) x ∑ l (9 - 6) + (4 - 6) + (10 - 6) + (9 - 6) + (5 - 6) + (2 - 6) + (10 - 6) + (3 - 6) + (3 - 6) + ( 5 - 6) = 3.2
