Multiple Choice

"There are many assets to using a field study," said the graduate student. "First, you're dealing with correlation, so you can draw conclusions about the direction of causality. Second, you have a high degree of control over confounding variables. Third, because you're dealing with a contrived situation, you're bound to have poor external validity. And fourth, your presence might influence the subjects' behavior." Which part of the graduate student's thinking was accurate ?

• B) This type of study affords a high degree of control over confounding variables.
• C) Because this type of study is contrived, it will result in poor external validity.
