Question

Quizplus · Accepted Answer

The correlation coefficient measures the strength and direction of a linear relationship between two variables. When the correlation coefficient is significantly different from zero, it indicates that there is a statistically significant relationship between the two variables. This means that it is possible to use the correlation coefficient to make predictions about one variable based on the value of the other variable. However, the accuracy of these predictions will depend on the strength of the correlation coefficient.
