Question

How would the value of the correlation coefficient, r, change if sodium was plotted on the x-axis and calories plotted on the y-axis?

A) The value of r would decrease.
B) The value of r would increase.
C) The value of r would remain the same.
D) The value of r cannot be determined from the information provided.

Answer 1

The value of the correlation coefficient, r, would depend on the relationship between sodium and calories.

Step-by-step explanation:

The value of the correlation coefficient, r, would change depending on the relationship between sodium and calories. If there is a positive correlation between sodium and calories, meaning that as sodium increases, calories also tend to increase, then the value of r would increase. On the other hand, if there is a negative correlation between sodium and calories, meaning that as sodium increases, calories tend to decrease, then the value of r would decrease. If there is no linear relationship between sodium and calories, the value of r would be close to zero.
