Answer:

Put the given data in ascending order:

  • 1, 1, 1, 1, 1, 2, 3, 3, 3, 3, 5, 9, 9, 9, 9, 9, 9, 9, 9, 9

Mean is the average of 20:

  • (1*5 + 2 + 3*4 + 5 + 9*10)/20 = 5.7
  • median = 5.7

Mode is the most repeated number:

  • mode = 9

Median is the average of the two middle numbers:

  • (3 + 5)/2 = 4
  • median = 4
