Answer:
Mean: 78.8
M.A.D(Mean Absolute Deviation): 2.3
Step-by-step explanation:
Mean: 73, 75, 76, 78, 78, 79, 79, 80, 81, 81, 82, 84 = 946/12 = 78.8
Mean Absolute Deviation (M.A.D):
78.8 - 73 = 5.8
78.8 - 75 = 3.8
78.8 - 76 = 2.8
78.8 - 78 = 0.8
78.8 - 78 = 0.8
78.8 - 79 = 0.2
78.8 - 79 = 0.2
78.8 - 80 = 1.2
78.8 - 81 = 2.2
78.8 - 81 = 2.2
78.8 - 82 = 3.2
78.8 - 84 = 5.2
5.8 + 3.8 + 2.8 + 0.8 + 0.8 + 0.2 + 0.2 + 1.2 + 2.2 + 2.2 + 3.2 + 5.2 = 28.4/12 = 2.3
