The positive and negative signs in the Pearson product-moment correlation coefficient provide information about the:
A)strength of a relationship.
B)true score of a measure.
C)direction of a relationship.
D)measurement error of a measure.

Question

Quizplus · Accepted Answer

The positive and negative signs in the Pearson product-moment correlation coefficient indicate the direction of a relationship between two variables. A positive sign indicates a positive relationship, while a negative sign indicates a negative relationship. The strength of the relationship is determined by the magnitude of the coefficient, while the true score of a measure and the measurement error of a measure are not directly related to the sign of the coefficient.
