Step-by-step explanation:
Find the Mean
80+82+90+92+86+74+68+88+90+98/10
848/10=84.8
Mean absolute deviation
(80-84.8)+(82-84.8)+(90-84.8)+(92-84.8)+(86-84.8)+(74-84.8)+(68-84.8)+(88-84.8)+(90-84.8)+(98-84.8)
simplify
(4.8) + (2.8) + (5.2) + (7.2) + (1.2) + (10.8) + (16.8) + (3.2) + (5.2) + (13.2)
Divide by 10
