Listed below are ages of Best Actresses and Best Actors at the times they won Oscars (from Data Set 14 “Oscar Winner Age” in Appendix B). Do these data suggest that there is a correlation between ages of Best Actresses and Best Actors?

Data Set 14: Oscar Winner Age 

Data are from 87 years (first five rows shown here). Data values are ages (years) of actresses and actors at the times that they won Oscars in the categories of Best Actress and Best Actor. The ages are listed in chronological order by row, so that each row has paired ages from the same year. (Note: In 1968 there was a tie in the Best Actress category, and the mean of the two ages is used; in 1932 there was a tie in the Best Actor category, and the mean of the two ages is used).

These data are suggested by the article “Ages of Oscar-Winning Best Actors and Actresses,” by Richard Brown and Gretchen Davis, Mathematics Teacher magazine. In that article, the year of birth of the award winner was subtracted from the year of the awards ceremony, but the ages listed here are calculated from the birth date of the winner and the date of the awards ceremony.
