Guess the pmcc
Click on New Plots. Four scatter plots will appear along the top (Plots A, B, C, and D), and four correlation coefficients will appear at the left below the first plot. There is exactly one correct correlation for each plot. To the right of each correlation coefficient, there is a set of four choices. Choose the one you think is the scatter plot with that correlation coefficient. (If two correlation coefficients are equal, either one can go with the plot.) Press the Answers button. The program will indicate which correlation coefficients you correctly matched, and show the number correct in the lower left. The lower right accumulates your score if you play more than once Just above the lower right, the number of plots you have gotten correct in a row is recorded. You need to guess all four correctly for your streak to continue. To play more, click on New Plots.
