Quizplus · Accepted Answer

The empirical rule can be used to determine the percentage of data values that must be within one, two, and three standard deviations of the mean for data having a bell-shaped distribution. Chebyshev's theorem can be used for any distribution and provides more general results, while a five-number summary and a box plot are graphical methods for summarizing data and do not provide information about the percentage of data values within a certain range.
