what is the mean absolute deviation of the following set of data? 8 10 10 8

Answer:

1

Explanation:

Step1: Calculate the mean

$\frac{8 + 10+10 + 8}{4}=\frac{36}{4}=9$

Step2: Calculate the absolute deviations

$|8 - 9|=1$, $|10 - 9|=1$, $|10 - 9|=1$, $|8 - 9|=1$

Step3: Calculate the mean absolute deviation

$\frac{1+1+1+1}{4}=\frac{4}{4}=1$
