Quizplus · Accepted Answer

The coefficient of variation (CV) is a ratio of the standard deviation to the mean expressed as a percentage. Therefore, the best choice for expressing the CV is as a percentage (choice B). A histogram (choice A) is a graphical representation of the distribution of data, while a box-and-whisker plot (choice C) and a five-number summary (choice D) are used to summarize the distribution of data but do not directly express the coefficient of variation.
