Quizplus · Accepted Answer

The degree or strength of a relationship between two variables is shown by the coefficient of correlation. This measures the linear relationship between two variables and ranges from -1 (perfect negative correlation) to 1 (perfect positive correlation), with 0 indicating no correlation. The other options (alpha, mean, mean absolute deviation, and cumulative error) do not specifically measure the strength of a relationship between variables.
