Simora [160]

Answer:

The MAD of {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

<u><em>Step 1 : Add all the values Up:</em></u>

<u><em /></u> $12+10+10+8+6+7+7+12=72$

<u><em>Step 2 : Divide them by the number of items or numbers:</em></u>

<u><em></em></u> $\frac{12+10+10+8+6+7+7+12}{8}=9$ <u><em></em></u>

<u><em></em></u>

<u><em>Step 3: Find the absolute deviations:</em></u>

<u><em></em></u> $12-9=3\\10-9=1\\10-9=1\\9-8=1\\9-6=3\\9-7=2\\9-7=2\\12-9=3\\$ <u><em></em></u>

<u><em>Step 4: Add all the absolute deviations:</em></u>

$3+1+1+1+3+2+2+3=16$
