Based on the attached picture, do people getting high pain scores on the U of W scale rate the cold water more painful? The two variables, the UofW Pain Inventory scores and the Cold Water ratings, may be operationally defined in different ways. A high score may either imply lots of pain or no pain. The way the measures were scaled/defined will affect whether you would expect a positive or a negative correlation. Please

Follow-up Question

Based on the correlation coefficient between scores on U of W Pain Inventory and the Marlowe-Crowne Reaction Inventory, is the obtained correlation coefficient consistent with the possibility that people with high levels of social desirability tend to say they would not react strongly when presented with a painful stimulus? Hint: Should the correlation coefficient between the Marlowe-Crowne Reaction Inventory and the U of W Pain Inventory be positive or negative if the “tough is socially desirable” hypothesis is true? In answering this question, you may assume that correlations that are less than +/- 0.2 are equivalent to zero.
