The difference between the mean and the median of the data is 1

Mean and median

Given data:

11, 12, 8, 12, 8, 8, 11, 11, 9

  • Mean = Sum of data ÷ number of data

= (11 + 12 + 8 + 12 + 8 + 8 + 11 + 11 + 9) / 9

= 90 / 9

= 10

  • Median = middle number

Arrange in ascending order

8, 8, 8, 9, 11, 11, 11, 12, 12

The middle number is 11

Therefore, the difference between the mean and the median of the data is 11 - 10 = 1
