The correlation coefficient measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, with values closer to -1 indicating a strong negative correlation, values closer to 1 indicating a strong positive correlation, and values close to 0 indicating no linear relationship. Therefore, the correlation coefficient is the best choice for measuring the strength of the relationship between two variables.
