Question

question 2 what is the interquartile range of the box plot below? 20 25 40 45

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 = 25 and Q3 = 45.

Step2: Calculate the interquartile range

The interquartile range (IQR) is given by the formula IQR=Q3 - Q1. Substituting the values of Q1 and Q3, we get IQR = 45 - 25.
IQR = 20

Answer:

20
