The sign of the correlation coefficient (r) indicates the direction of the relationship between the two variables. If r is positive, the variables have a positive correlation, meaning they increase or decrease together. If r is negative, the variables have a negative correlation, meaning as one variable increases, the other decreases. The absolute value of r indicates the strength of the relationship, where values closer to 1 indicate a stronger correlation. Therefore, examining the sign of the correlation coefficient is the best choice for determining the nature of the relationship between two correlated variables.
