Question: 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 age he or she would be open to in a romantic prospect. So, if someone was 23 years old and would date someone as old as 30, his or her score would be 7; if someone was 25 and would date someone as old as 23, his or her score would be 2. He calculated these scores for all 200 posters and categorized them into male versus female and homosexual versus heterosexual.
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.
