Question

find the interquartile range of the data set represented on the box plot.

Explanation:

Step1: Identify Q1 and Q3

From the box plot, the left end of the box (Q1) is at 280, and the right end of the box (Q3) is at 560.

Step2: Calculate IQR

The interquartile range (IQR) is calculated as \( IQR = Q3 - Q1 \). Substituting the values, we get \( IQR = 560 - 280 = 280 \).

Answer:

280
