Bivariate CorrelationA Measure of Relationship

The correlation coefficient (r)is an index that describes the extent to which two sets of dataare related; it is a measure of the relationship between two

variables and ranges in values between -1.00 and +1.00, inclusive.

The sign indicates the direction of the relationship,where a plus (+) indicates a positive relationship,

and a negative (-) indicates a negative relationship.The absolute value of the coefficient indicates the magnitude of the relationship.

Bivariate CorrelationA Measure of Relationship

A perfect positive (direct) correlation coefficient is +1.00.A positive relationship indicates that as one score goes up, the other

score goes up – or – as one score goes down, the other score goes down.That is, the value on one variable follows the value on the other.

A perfect negative (inverse) correlation coefficient is -1.00.A negative relationship indicates that as one score goes up, the other score goes down.

When there is no relationship between two variables –the correlation coefficient is 0.00 (zero).

All other possible values (i.e., excluding +1.00, -1.00, and 0.00)are considered imperfect relationships (both positive and negative).
