Answer:
The MAD of {12, 10, 10, 8, 6, 7, 7, 12} is 2.
Step-by-step explanation:
Step 1 : Add all the values Up:
[tex]12+10+10+8+6+7+7+12=72[/tex]
Step 2 : Divide them by the number of items or numbers:
[tex]\frac{12+10+10+8+6+7+7+12}{8}=9[/tex]
Step 3: Find the absolute deviations:
[tex]12-9=3\\10-9=1\\10-9=1\\9-8=1\\9-6=3\\9-7=2\\9-7=2\\12-9=3\\[/tex]
Step 4: Add all the absolute deviations:
[tex]3+1+1+1+3+2+2+3=16[/tex]
Step 5: Find the mean:
[tex]\frac{3+1+1+1+3+2+2+3}{8}=2[/tex]
