Answer:

Step-by-step explanation:

(a)

Data Set 1

  • Mean : 70 + 65 + 72 + 80 + 73 / 5
  • Mean = 357/5 = 71.4
  • Deviation from Mean : 1.4 + 6.4 + 0.6 + 8.6 + 1.6 / 5
  • M.A.D = 18.6/5 = 3.72

Data Set 2

  • Mean : 61 + 47 + 70 + 63 + 54 / 5
  • Mean : 295/5 = 59
  • Deviation from Mean : 2 + 12 + 11 + 4 + 5 / 5
  • M.A.D. = 34/5 = 6.8

Comparison

  • On comparing the Mean Aboslute Deviation values of the two games, it is seen that that the Leaping Lizards game has a higher MAD than the Jumping Jackrabbits game, which means the scores deviate more in the Leaping Lizards game, whereas in the other game it is consistent
