Correlation definition is - the state or relation of being correlated; specifically : a relation existing between phenomena or things or between mathematical or statistical variables which tend to vary, be associated, or occur together in a way not expected on the basis of chance alone. If relevant, also compare the zero-order and partial correlation coefficients, and possibly also the unique variance explained for each predictor (the semi-partial correlation squared – which is from the “part” column in an SPSS coefficients table).
