Distribution family

In statistics, a "distribution family" refers to a group of probability models that share common characteristics and assumptions. These models describe how data values are spread or distributed, such as how often certain outcomes occur. For example, the normal family includes the familiar bell-shaped curve, while the Poisson family models the number of events happening over time. Using a distribution family helps statisticians choose the right model to analyze data effectively, understand underlying patterns, and make accurate predictions based on the type of data they are studying.
