The interquartile range of the data set is 60

What is the interquartile range of the data set?

The interquartile range of the data set is the difference between the lower quartile (Q1) and the upper quartile (Q3)

From the given information:

  • Data set = 1, 5, 12, 14, 29, 45, 48, 61, 72, 84, 96

We need to first identify the middle number(median) = 45

Thus:

  • Q1  = (1+ 5+ 12+ 14+ 29)/5
  • Q1 = 12.2

  • Q3 = (48+ 61+ 72+ 84+ 96)/5
  • Q3 = 72.2

IQR = 72.2 - 12.2

IQR = 60
