The correlation coefficient is a statistical measure that describes the strength and direction of a relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 signifies no correlation. Understanding this measure is crucial in simple linear regression as it helps determine how well the independent variable can predict the dependent variable.
