Question

1. which display makes it easier to find that the interquartile range is 4 songs? choose 1 answer: a the dot plot b the box plot

Explanation:

A box plot (or box - and - whisker plot) is designed to show the five - number summary of a data set: minimum, first quartile ($Q_1$), median, third quartile ($Q_3$), and maximum. The interquartile range (IQR) is calculated as $IQR = Q_3 - Q_1$. In a box plot, the length of the box represents the interquartile range, and we can easily identify the values of $Q_1$ and $Q_3$ from the box. A dot plot shows the frequency of individual data points, and to find the interquartile range from a dot plot, we would need to first order the data and then identify the quartiles, which is more time - consuming and less straightforward than using a box plot.

Answer:

B. The box plot
