Question

Suppose a study finds that the correlation coefficient relating job satisfaction to salary is r=1. Which of the following are the proper conclusions?

I. High salary causes high job satisfaction.
II. Low salary causes low job satisfaction.
III. There is a very strong association between salary and job satisfaction.


I and II only

I, II and III

III only

I only

Answer 1

The correct conclusion from a correlation coefficient of r=1 is that there is a very strong association between salary and job satisfaction; however, we cannot infer causality between salary and job satisfaction just from the correlation.

Step-by-step explanation:

If a study finds that the correlation coefficient relating job satisfaction to salary is r=1, one of the proper conclusions we can make is option III: There is a very strong association between salary and job satisfaction. A correlation coefficient of 1 indicates a perfect positive linear relationship between two variables. However, it is important to note that correlation does not imply causation, so we cannot conclude that high salary causes high job satisfaction (I) or that low salary causes low job satisfaction (II) based solely on the correlation coefficient.

Research has indicated that the relationship between salary and job satisfaction might not be as strong as other job factors like the work-content factor. Therefore, we should be cautious in drawing any conclusions about causality from a correlation coefficient.

Answer 2

its I, II and III.

Step-by-step explanation:

r values are from -1 to 1, if the value is 0 means there's no connection between values of variables, if its lower than 0, if the value of variable goes up the other goes down, if its higher than 0, than if one value of variable increases than the value of other variable increases too. the closer to 1 the stronger the association.
