In the file Hair.sav, on Karl's SPSS Data Page, are data relative to assortative mating with respect to hair color. Each row in the data file represents one cell in the 2 x 2 x 2 contingency table, with the freq variable already set as the weighting variable. Variable Hair_S is the respondent's hair color, Hair_M is the hair color the respondent wanted e's mate to have, and Gender is the respondent's gender. There are two values of Hair Color: Blonde and Black/Brown. To avoid very small expected frequencies, I excluded data from participants who indicated that they had, or desired their mate to have, red, gray, or white hair.

You do a complete analysis, testing the research hypothesis that individuals prefer mates similar to themselves. Write up your results in an APA-style results section and attach it to email to Karl. Be prepared to discuss your results in class and to show your statistical output to any interested parties.
