Question

the five number summary of a data set was found to be: 48, 52, 58, 66, 69. what is the interquartile range?

Explanation:

Step1: Identify Q1, Q3

In a five - number summary (min, Q1, median, Q3, max), for the set 48, 52, 58, 66, 69, Q1 = 52 and Q3 = 66.

Step2: Calculate IQR

The inter - quartile range (IQR) is calculated as IQR=Q3 - Q1. So, IQR = 66 - 52.
IQR = 14

Answer:

14
