The mean and mean absolute deviation of the given set of data in sample 1 are; 10 and 4.32 respectively

How to find Mean and Mean Deviation?

Mean of a set of numbers or data is;

x' = ∑x/n

In this case, the mean is;

∑x = 16 + 11 + 9 + 12 + 11 + 10 + 10 + 8 + 15 + 0 + 2 + 15 + 14 + 7 + 11 + 5 + 14 + 20 + 3 + 11 + 13 + 7 + 0 + 5 + 21

∑x = 250/25

∑x  = 10

Formula for mean absolute deviation is;

m = (x₁ - x') + (x₂ - x') + .....(xₙ - x')

From online calculator, m = 4.32
