Amplitude = 12 - 2 = 10

 

MédiaA = (2 + 3 + 4 + 5 + 7 + 10 + 12) / 7 = 43 / 7 = 6,1428

DesvioMedioA = |2-6,1428|+|3-6,1428|+|4-6,1428|+|5-6,1428|+|7-6,1428| + |10-6,1428| + |12-6,1428|  / 7
DesvioMedioA = (4,1428 + 3,1428 + 2,1428 + 1,1428 + 0,8572 + 3,8572 + 5,8572 ) /7
DesvioMedioA = 21,1428 / 7
DesvioMedioA = 3,0204
