Answer:

  • Median = 6
  • IQR = 3

Step-by-step explanation:

Given data:

  • 8, 5, 6, 6, 4, 9, 7, 6, 5, 9

Put this into ascending order:

  • 4, 5, 5, 6, 6, 6, 7, 8, 9, 9

Median is 6 as both middle numbers are same = 6

Split the data into lower and upper halves:

  • (4, 5, 5, 6, 6)(6, 7, 8, 9, 9)

Q1 is the median of the lower half:

  • Q1 = 5

Q3 is the median of the upper half:

  • Q3 = 8

IQR is the difference of Q3 and Q1

  • IQR = 8 - 5 = 3
