July 17, 2020Do these two variables seem to have a strong linear relationship?
For the paired z scores in the following table compute the value for Pearsons r using the z score formula and then answer the questions that follow. [Note that these sets of scores look like z scores but each set does not actually have a mean of zero and SD of 1.0. Nonetheless this exercise will give you practice with the z score formula and the result is realistic.]

1. Do these two variables seem to have a strong linear relationship? Draw a graph and describe what you see.
2. What value did you calculate for Pearsons r? Given the scatter of the points in the graph that you drew for question 1 does the overall Pearsons r for these data come as a surprise to you? Why or why not?
