population correlation coefficient

(symbol: ρ) an index expressing the degree of association between two continuously measured variables for a complete population of interest. For example, a researcher could obtain income and education information for all families in a town and calculate a population correlation coefficient for the entire town. In contrast, the sample correlation coefficient indexes the association for a specific subset of those cases (e.g., every fourth family from a list of all those in the town).
