Exam 2: Research Methods in Psychology

We can predict participants' scores on Variable A with perfect accuracy by knowing their scores on Variable B,and higher scores on Variable A are associated with lower scores on Variable B.What is the correlation coefficient for the correlation between Variables A and B?

If Variable X is increasing at about the same rate as Variable Y is decreasing,what can you conclude?

The closer a correlation coefficient gets to +1.00 or -1.00,the more scattered are the data points on a graph.
