A researcher wondered about the degree to which age was a factor for those posting personal ads on Match.com. He randomly selected 200 ads and examined data about the posters (the people who posted the ads). Specifically, for each ad, he calculated the difference between the poster’s age and the oldest acceptable age in a romantic prospect. So, if someone were 23 years old and would date someone as old as 30, his or her score would be 7; if someone were 25 and would date someone as old as 23, his or her score would be −2. The researcher then categorized the scores into male versus female and seeking a same-sex date versus seeking an opposite-sex date.

a. List any independent variables, along with the levels.

b. What is the dependent variable?

c. What kind of ANOVA would he use?

d. Now name the ANOVA using the more specific language that enumerates the numbers of levels.

e. Use your answer to part (d) to calculate the number of cells. Explain how you made this calculation.

f. Draw a table that depicts the cells of this ANOVA.
