Final answer:
The closer the absolute value of r is to 1, the stronger the correlation between 2 variables.
Step-by-step explanation:
The closer the absolute value of r (correlation coefficient) is to 1, the stronger the correlation between 2 variables.
The correlation coefficient, r, measures the strength of the linear association between x and y. Values of r close to −1 or to +1 indicate a stronger linear relationship between x and y. For example, if r = 0.9, it indicates a far stronger relationship than if r = 0.3.
Therefore, option 2) stronger is the correct answer.
