The population (universe) from which observations are drawn, categorized into cells, and form identifiable patterns. It is based on the concept of variation that states that anything measured repeatedly will arrive at different results. These results will fall into statistically predictable patterns. A bell-shaped curve (normal distribution) is an example of a distribution in which the greatest number of observations occur in the center with fewer and fewer observations falling evenly on either side of the average.
Distribution is a way of describing the output from a system of variation. The distribution's location, shape, and spread may be evaluated by statistics such as the mean, median, sigma, and range.
