RIDDLE: Why did the hippies get married in a bath tub?

Directions: To find the answer to the riddle, write “T” for “true” or “F” for “false”.

1. ___ For a Pearson r of 0.50, the coefficient of determination equals 0.25. (IN)

2. ___ For a Pearson r of -0.60, the coefficient of determination equals 0.36. (ORDER)

3. ___ For a Pearson r of 0.75, 75% of the variance on one variable is explained by (i.e., is accounted for by) the other. (LOVE)

4. ___ For a Pearson r of -0.40, 40% of the variance on one variable is explained by the other. (WILL)

5. ___ For a Pearson r of 0.90, 81% of the variance on one variable is explained by the other. (TO)

6. ___ For a Pearson r of 0.80, 36% of the variance on one variable is NOT explained by the other. (HAVE)

7. ___ The Pearson r may be thought of as a proportion that, when multiplied by 100, yields the percent of variance on one variable explained by the other. (BECOME)

8. ___ The square of the Pearson r is known as the “coefficient of determination.” (A)

9. ___ For a Pearson r of -0.36, the coefficient of determination equals —0.06. (COUPLE)

10. ___ For a Pearson r of -0.22, about 95% of the variance on one variable is NOT explained by the other. (DOUBLE)

11. ___ For a Pearson r of —0.62, a majority of the variance on one variable is explained by the other. (CLEAN)

12. ___ For making predictions from one variable to another, a Pearson r of -0.78 is better than a Pearson r of 0.52. (RING)

13. ___ A simple correlational study is usually NOT suitable for identifying causeand-effect relationships. (CEREMONY)
