Lets assume that the data from a recent study indicate that there is a strong relationship between test scores and amount of time spent watching television. Students who watch more television tend to perform worse on tests. Which of the following BEST represents the relationship just described?

Select one:
A. +.30
B. -.83
C. -.25
D. +.74

B. -.83

Explanation:

The result from the study of the data is negatively correlated, thus a correlation coefficient of -0.83 is the best representation of the relationship between television watching and test performance.

Correlation is simply the relationship between two variables. Correlation can be positive if an increase in one variable results in an increase in the other or it can be negative if an increase in one variable results in a decrease in the other. Example, an increase in television watching duration resulting in a decrease in test score is a negative correlation.
