Final answer:
The value of r represents the correlation coefficient, which measures the strength and direction of the linear relationship between two variables. If r is negative c. showing a decrease.
Step-by-step explanation:
The value of r represents the correlation coefficient, which measures the strength and direction of the linear relationship between two variables
If r is positive, it indicates a positive correlation, meaning that as one variable increases, the other variable tends to increase as well. If r is negative, it indicates a negative correlation, where as one variable increases, the other variable tends to decrease.
If r is zero, it indicates no linear relationship between the variables.
