Question

From the following data, find: 

Inter-quartile range

25, 10, 40, 88, 45, 60, 77, 36, 18, 95, 56, 65, 7, 0, 38 and 83 

 

Solution

Interquartile range= 

`q_1=(16"th")/4 "term" = 18 ; q^3=65` 

Interquartile range = q3 - q1 

∴ `q_3-q_1=65-18`

= 47

  Is there an error in this question or solution?
