How does the value of r relate to how easy it is to estimate the least-squares fit line?
Question
Solution 1
The value of r, also known as the correlation coefficient, measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1.
- If r is close to 1 or -1: This indicates a strong linear relationship between the two variables. If r is 1, it means there's a Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
