The histogram above follows a very uniform pattern as every bar is almost exactly the same height. This type of pattern shows up in some types of probability experiments. For example, if you were to take a 6 sided fair die and roll it many times (as in 100+) you would get a pattern that is approximately uniform.

A histogram is bell-shaped if it resembles a "bell" curve and has one single peak in the middle of the distribution. The most common real-life example of this type of distribution is the normal distribution. 2. Uniform. A histogram is described as "uniform" if every value in a dataset occurs roughly the same number of times.
