Question 2 0 pts

I showed you a curvilinear relationship between age and memory. Now, I want you come up with two variables that you think might have a curvilinear relationship (not a linear relationship)! Write down your answers for your Pause-Problem (Note: I am actually looking for only one real answer here. You need two variables in this one answer, as I need to see how one variable correlates with the second).

Question 4 0 pts

You saw this question and answer in the powerpoint as a pop quiz. If the coefficient of determination between two variables is .81, what is the Pearson correlation coefficient? The answer was .90. Tell me why it is .90 in your Pause Problem!

Question 5 0 pts

Make sure to give me a Pop Quiz question with the correct answer. I may not use it this semester, but it might turn up in the future for other students.
