The box plot represents the number of tickets sold for a school dance.

A horizontal line labeled Number of Tickets sold that starts at 11, with tick marks every one unit up to 25. The graph is titled Tickets Sold for A Dance. The box extends from 17 to 20 on the number line. A line in the box is at 19. The lines outside the box end at 12 and 24.

Which of the following is the appropriate measure of variability for the data, and what is its value?

The IQR is the best measure of variability, and it equals 3.
The range is the best measure of variability, and it equals 12.
The IQR is the best measure of variability, and it equals 12.
The range is the best measure of variability, and it equals 3.

Answer 1

The IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the box extends from 17 to 20, so Q1 is 17 and Q3 is 20. Thus, the IQR is 20 - 17 = 3.

Therefore, the appropriate measure of variability for the data is the IQR, and its value is 3.

Option A ("The IQR is the best measure of variability, and it equals 3") is the correct answer
