Question

the box plot below represents some data set. what is the interquartile range (iqr) of the data?

Explanation:

Step1: Identify Q1 and Q3

Q1 is the left - hand edge of the box and Q3 is the right - hand edge of the box. From the box - plot, Q1 = 100 and Q3 = 150.

Step2: Calculate the IQR

The formula for the inter - quartile range is IQR=Q3 - Q1. Substitute Q1 = 100 and Q3 = 150 into the formula: IQR=150 - 100.

Answer:

50
