Question

A correlation coefficient represents two things: ________ and ________.

A. a representative sample; strength

B. direction of the relationship; expectant functionality

C. the experimental group; control group

D. strength; direction of the relationship

Answer 1

A correlation coefficient represents the strength and direction of the relationship between variables. The closer the coefficient is to 1 (positive or negative), the stronger the relationship.

Step-by-step explanation:

A correlation coefficient represents two things: strength and direction of the relationship. The number portion of the correlation coefficient indicates the strength of the relationship.

The closer the number is to 1 (be it negative or positive), the more strongly related the variables are, and the more predictable changes in one variable will be as the other variable changes.
