Question
Find the interquartile range (IQR) of the data set.
- 20
- 25
- 5
- 10
Hint:
The interquartile range (IQR) is the difference between the upper quartile and the lower quartile.
The correct answer is: 20
Step 1 of 1:
The above diagram is of a boxplot, mentioning Q3 (third quartile) and Q1 (first quartile).
In the given diagram,
observe that, Q3 = 50 and Q1 = 30
So, the IQR is Q3 - Q1 = 50 – 30 = 20
Final Answer:
The right choice is-- a. 20
