Question

PLS HELP ME
What is the mean absolute deviation of the data 10, 17, 20, 12, and 16? Round to the nearest whole number

Answer 1

Answer:

3.5

Step-by-step explanation:

where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.

Answer 2

Answer:

The answer is 4

$s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }$

Turn the equation into a simpler form

$s = \sqrt{\frac{SS}{n-1} }$

$s = \sqrt{\frac{64}{5-1} }$

$s = \sqrt{\frac{64}{4} }$

$s = \sqrt{16}$

That said, we know the square root of 16 is 4, so 4 would be your answer.

$s = 4$
