22. the box plot below represents some data set. what is the interquartile range (iqr) of the data? 15 20 25 30 35 40
Answer
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 = 20 and Q3 = 30.
Step2: Calculate the IQR
The inter - quartile range (IQR) is calculated as IQR=Q3 - Q1. Substitute Q1 = 20 and Q3 = 30 into the formula: IQR = 30−20.
