Mathematics/Statistics/Distributions

A distribution of a data set is essentially a graph that shows all values of data and how often they occur.

For an ordered data set, the x-axis denotes the values of the data. The y-axis denotes the frequency of each specific value.

Normal Distribution

Also known as a bell curve.

A normal distribution is based on continuous numerical data, where 68% of data is centered around the mean. The farther from the mean, the less frequently values occur. This distribution is symmetrical.
