Guessing Correlations Simulation
Begin by answering the questions, even if you have to guess. The first time you answer the questions you will not be told whether you are correct or not.
Once you have answered all the questions, answer them again using the simulation to help you. This time you will get feedback about each individual answer.
This demonstration does not have questions associated with it. Use it to improve your understanding of what scatter plots of data with different values of r lool like.
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.
