Definition
A Distribution describes how the values of a variable are arranged across a dataset.
Human Explanation
It shows which values occur, how often they occur and how they are spread.
Why it Matters
Understanding the distribution of data helps analysts select appropriate methods and interpret results correctly.
Conceptual Boundary
A Distribution does not describe a relationship between variables. It describes the pattern of values for a single variable, although joint distributions can extend the idea to multiple variables.
Practical Perspective
Examining the shape, centre, spread and unusual values of a distribution is one of the first steps in statistical analysis.
