Dr.Patel investigates semantic learning among college students as a function of the number of exposures to given material on the one hand,and the number of diverse types of exposures (e.g.,reading,listening,writing)to the material on the other.Which of the following pairs of coefficients should she find between learning scores and the number of exposures and between learning scores and the number of types of exposures?
A) learning scores and number of exposures:.30; learning scores and number of types of exposures: -.30
B) learning scores and number of exposures:.30; learning scores and number of types of exposures:.30
C) learning scores and number of exposures:.30; learning scores and number of types of exposures:.00
D) learning scores and number of exposures:.00; learning scores and number of types of exposures:.30

Based on the information given, we can assume that both the number of exposures and the number of types of exposures will have a positive correlation with learning scores. Therefore, both coefficients should be positive. As for the strength of the correlation, we can expect it to be moderate, which would correspond to a coefficient of around .30. Choice B is the only one that meets these criteria, with both coefficients at .30.
