When researchers are interested in predicting some future behavior based on a person's score on some other variable, they should:
A)construct several criterion variables.
B)construct a scatterplot in addition to looking at the magnitude of the correlation coefficient.
C)demonstrate that there is a reasonably high correlation between the criterion and predictor variables.
D)demonstrate that the correlation coefficient of the known and the unknown variable is closer to -1.00.

Question

Quizplus · Accepted Answer

In order to predict future behavior based on a person's score on some other variable, researchers should demonstrate that there is a reasonably high correlation between the criterion and predictor variables. This indicates that there is a strong relationship between the two variables, and makes it more likely that the predictor variable can be used to accurately predict future behavior. It is not necessary to construct several criterion variables or to demonstrate that the correlation coefficient is closer to -1.00. While constructing a scatterplot may be helpful in visualizing the relationship between the two variables, it is not necessary for demonstrating the strength of the correlation.
