Answer:
M.A.D = 12.1
Step-by-step explanation:
1. Find the mean:
Add all values and then divide by 10
[tex]\frac{497}{10\\}[/tex]= 49.7
2. Subtract each value from the mean, each value stays positive
40-49.7= |-9.7| = 9.7
55-49.7= |5.3| = 5.3
60-49.7= |10.3| = 10.3
48-49.7= |-1.7| = 1.7
57-49.7= |7.3| = 7.3
33-49.7= |-16.7| = 16.7
57-49.7= |7.3| = 7.3
20-49.7= |-29.7| = 29.7
80-49.7= |30.3| = 30.3
47-49.7= |-2.7| = 2.7
3. Add all the final values and divide by 10
4. [tex]\frac{121}{10}[/tex]= 12.1
