Question

Outliers are clearly presented in a A) Dot plot. B) Stem-and-leaf display. C) Box plot. D) Contingency table.

Answer 1

C) Box plot

Explanation:

• A box plot is a graphical representation of data that displays the distribution of a dataset using five summary statistics: the minimum, first quartile, median, third quartile, and maximum.
• Outliers are typically defined as data points that fall outside of the whiskers of the box plot, which extend from the first and third quartiles to the minimum and maximum values within 1.5 times the interquartile range.
• These outliers are usually plotted as individual points outside of the whiskers, making them easy to identify.
