Question

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

Explanation:

Step1: Identify Q1 and Q3

In a box - plot, the left - hand side of the box is the first quartile (Q1) and the right - hand side of the box is the third quartile (Q3). From the box - plot, Q1 = 50 and Q3 = 100.

Step2: Calculate the IQR

The formula for the inter - quartile range is IQR=Q3 - Q1. Substitute Q1 = 50 and Q3 = 100 into the formula. So, IQR = 100 - 50.

Answer:

50
