Which of the following can be used to measure the shape of a distribution?

A) mean
B) mode
C) kurtosis
D) median

Kurtosis is a measure of the peakedness and thickness of the tails of a distribution. A high kurtosis value indicates a more peaked distribution, while a low kurtosis value indicates a flatter distribution. Therefore, kurtosis is the best choice for measuring the shape of a distribution. Mean, median, and mode are measures of central tendency and do not provide information about the shape of a distribution.
