Quartiles are values that divide a set of data into four equal parts. So A data set has three quartiles: the lower quartile, the median of the data set, and the upper quartile. media is the median divides a data set into two equal parts. Lower quartile is the median of the lower half of the data. Upper quartile is the median of the upper half of the data.

What is the product of all the three quartiles of the box-and-whisker plot shown?

Choices:
A. 2,050
B. 2,431
C. 1,234
D. 41
Correct Answer: B
Solution:
Step 1: The middle quartile = 13 and the upper quartile = 17.
Step 2: The product of all the three quartiles = lower quartile × middle quartile × upper quartile = 11 × 13 × 17 = 2,431 [Multiply.]
