Guessing Correlations Simulation

We recommend that you begin by answering questions before interacting with the simulation.


General Instructions


This demonstration allows you to learn about Pearson’s correlation by viewing scatter plots with different values of Pearson’s r. In each case, you will have an opportunity to guess the correlation. With a little practice, you should get pretty good at it.


Step By Step Instructions


Click the button next to the correlation that you think is present in the scatter plot. You will find out if you were right or wrong. If you were wrong, try another value. Then click the “New data” button.


Summary


After looking at a series of scatterplots, you should have a pretty good feel for what a certain value of r means.






Questions


Begin by answering the questions, even if you have to guess. The first time you answer the questions you should not check your answers. Once you have answered all the questions, answer them again using the simulation to help you. The second time through click the “Check Answer” button to get feedback.
