Coefficient Definition: Statistics

A coefficient measures a certain property or characteristic of a data set, phenomenon, or process, given specified conditions. You’ll come across many different coefficient definitions, each of which is specific to a test or procedure:

Correlation coefficients

These tell us whether two sets of data are connected:

Reliability Coefficients

Coefficients that measure agreement

>Coefficients that measure agreement (e.g. two judges agreeing on a certain ranking) include:

Other types of coefficients:

Coefficient Definition in Mathematics

In general mathematics, a coefficient is the number or multiplicative factor that goes before a variable in an equation or mathematical sentence.

If coefficients are numbers, they don’t change as the variables change, and we call them constants. They act upon the variables in a way that is always the same.

In the equation 4 x2 + 3 x, both 4 and 3 are coefficients. The coefficient of x2, 4, acts on the x2 term and multiplies it by 4. The coefficient of x, 3, acts on the x term and multiplies it by 3.
