A researcher conducts an experiment to establish a relationship between a chess player's mental stability and his performance in the game. He finds that the two have a Pearson product-moment correlation coefficient value of +1.00. This means the two variables-mental stability and performance-have a _____ relationship.
A)negative linear
B)curvilinear
C)nonlinear
D)positive linear

Question

Quizplus · Accepted Answer

A Pearson product-moment correlation coefficient value of +1.00 indicates a perfect positive linear relationship between the two variables, meaning that as one variable (mental stability) increases, the other variable (performance) also increases in a linear manner.
