Question

The correlation coefficient between two variables is r = 0.12. Which statement below is appropriate in this case? A. Because the correlation is so low, there is no point in studying this relationship further. B. The low correlation indicates that a linear relationship between x and y is not very strong, but there may be a different relationship between the two variables. We need to look at a scatterplot. C. The correlation between x and y is low, but that does not matter. We can still use least-squares regression to calculate an equation of the form = ax + b. D. None of the above.

Explanation / Answer

Option B is correct answer.

if there is low correlation then they implies that the linear relationship between X and Y is not strong, but there may be other relationship among them. And such relationship find out by plotting Scatter plot of X and Y
