Question

Find the interquartile range (IQR) of the data set.

  1. 20
  2. 25
  3. 5
  4. 10

hintHint:

The interquartile range (IQR) is the difference between the upper quartile and the lower quartile.

The correct answer is: 20


    Step 1 of 1:

    The above diagram is of a boxplot, mentioning Q3 (third quartile) and Q1 (first quartile).
    In the given diagram,

    observe that, Q3 = 50 and Q1 = 30
    So, the IQR is Q3 - Q1 = 50 – 30 = 20
    Final Answer:
    The right choice is-- a. 20
