what is the interquartile range of the data shown in the box plot?
Answer
Explanation:
Step1: Identify Q1 and Q3
In a box - plot, the left - hand side of the box is Q1 and the right - hand side is Q3. From the box - plot, Q1 = 68 and Q3 = 82.
Step2: Calculate inter - quartile range
The formula for the inter - quartile range (IQR) is IQR=Q3 - Q1. So, IQR = 82−68. IQR = 14
Answer:
14
