Uniform distribution

A uniform distribution is one in which every outcome or interval of equal size is equally likely, giving a flat shape.

In a uniform distribution the graph is level because no value is favored over another. For example, rolling a fair six-sided die gives each face a probability of 1/60.1671 / 6 \approx 0.167. For a continuous uniform distribution on an interval, the density is constant and probability equals the fraction of the interval covered. A flat dotplot or histogram is the visual signature of uniformity.
