Question

Quizplus · Accepted Answer

A correlation coefficient is a numerical index that measures the strength and direction of the relationship between two variables. It ranges from -1 to +1, with values closer to -1 or +1 indicating a stronger correlation and values closer to 0 indicating a weaker correlation. An independent variable is a variable that is manipulated or controlled by the researcher in an experiment, while a survey coefficient and experimental coefficient are not commonly used terms in statistics.
