Alan recorded the points he scored on the basketball court in ms2 school yard. What is the mean absolute deviation of his scores

The mean absolute deviation is: 7.44

Step-by-step explanation:

Given

Required

The mean absolute deviation

First, calculate the mean

The mean absolute deviation (M) is:

So, we have:

Remove absolute brackets

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
