Answer: A box plot
Explanation:
A box plot (also called a box-and-whisker plot) is an appropriate graph to represent the interquartile range. The box plot displays the five-number summary of a dataset: the minimum value, the first quartile (Q1), the median (Q2), the third quartile (Q3), and the maximum value. The box in the middle of the plot represents the interquartile range (IQR), which is the difference between the third and first quartiles. The whiskers extend from the box to the smallest and largest values that are not outliers.
Box plots are useful for comparing the distribution of multiple datasets and identifying any outliers. They provide a visual summary of the central tendency, variability, and skewness of a dataset.
