The Pearson product-moment correlation coefficient:
A)is called the Pearson c.
B)is used when both variables have ordinal or nominal scale properties.
C)provides information about the strength of a relationship.
D)does not indicate the direction of a relationship.

Question

Quizplus · Accepted Answer

The Pearson product-moment correlation coefficient is used to measure the degree and strength of a linear relationship between two continuous variables. It can range from -1 to 1, with a value of 0 indicating no relationship, a value of 1 indicating a perfect positive relationship, and a value of -1 indicating a perfect negative relationship. It does not provide information about the direction of the relationship. Option A is incorrect as the correlation coefficient is simply called the Pearson correlation coefficient. Option B is incorrect as the Pearson correlation coefficient can only be used for variables that have interval or ratio scale properties.
