Answer:

4

Step-by-step explanation:

Finding the mean :

  • 105 + 106 + 120 + 111 + 109 + 104 + 110 + 115 / 8
  • 880/8
  • 110

Absolute Mean Deviation of each term :

  • |110 - 105| = 5
  • |110 - 106| = 4
  • |120 - 110| = 10
  • |111 - 110| = 1
  • |110 - 109| = 1
  • |110 - 104| = 6
  • |110 - 110| = 0
  • |115 - 110| = 5

M.A.D. = 5 + 4 + 10 + 1 + 1 + 6 + 0 + 5 / 8

  • 32/8
  • 4
