A histogram depicts the shape of the distribution. It presents data in such a way where is it easy to know whether it is a normal or a skewed distribution and if there are any outliers. A frequency polygon depicts the more-than and less-than cumulative frequencies. On the other hand, the steam-and-leaf plot gives equal importance to each and every value, while also indicating the shape of the distribution.
