Data Set 18 “Speed Dating” in Appendix B includes data from 199 dates. Due to the large size of this data set, the data are available at www.TriolaStats.com. Download the data set and proceed to investigate correlations between pairs of variables using the data in the 5th, 7th, and 9th columns, which are all based on responses by females. Use the “like” measures by females as the y variable in each case.

1. Is there a correlation between “like” measures and attractiveness measures?

2. Is there a correlation between “like” measures and attribute measures?

3. Is there a correlation between attractiveness measures and attribute measures?

4. If Section 10-5 (Multiple Regression) was covered, investigate correlation and regression using the “like” measures as the y variable and use the attractiveness measures and attribute measures as the other two x variables.

5. Repeat the above using the 6th, 8th, and 10th columns, which are all based on responses by males.

6. Based on the results, what do you conclude? Write a brief report and include appropriate computer results.
