Association vs. Correlation: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 19, 2023
Association refers to any relationship between variables, while correlation quantitatively measures the linear relationship between two variables.

Key Differences

Association in statistics implies a general relationship or linkage between two or more variables. In contrast, correlation specifically refers to a statistical measure that expresses the extent to which two variables change together.

An association does not necessarily imply a cause-and-effect relationship, merely that variables are related in some way. Correlation, however, quantifies the degree to which one variable moves in relation to another.

Associations are often identified through patterns or trends in data but are not quantified. Correlation is typically measured using a correlation coefficient, such as Pearson's or Spearman's rho, which indicates the strength and direction of the linear relationship.

Detecting an association is often the first step in data analysis, which may lead to further investigation of correlations. Correlation analysis is used to test specific hypotheses about the nature of relationships between variables.

Association alone does not imply causation; two associated variables may not have a direct cause-and-effect link. Correlation also does not imply causation but provides a more specific framework for understanding how variables are related.
