Answer:

Data set A

  • 1, 2, 2, 2, 3, 4, 5
  • Mean = (1 + 2*3 + 3 + 4 + 5)/7 = 2.71
  • Mode = 2
  • Median = 2
  • Mean > median ⇒ Skewed right

Data set B

  • 1, 2, 3, 4, 4, 4, 5, 6, 7
  • Mean = (1 + 2 + 3 + 4*3 + 5 + 6 + 7)/9 = 4
  • Mode = 4
  • Median = 4
  • Mean = median ⇒ Symmetrical

Data set C

  • 1, 1, 2, 2, 3, 3, 4, 4
  • Mean = (1*2 + 2*2 + 3*2 + 4*2)/8 = 2.5
  • Mode = none
  • Median = (2+3)/2 = 2.5
  • Mean = median ⇒ Uniform

Data set D

  • 1, 2, 3, 4, 5, 5, 5, 6
  • Mean = (1 + 2 + 3 + 4 + 5*3 + 6)/8 = 3.875
  • Mode = 5
  • Median = (4+5)/2 = 4.5
  • Mean < Median ⇒ Skewed left
