In a study of simulated juror decision making, Braden-Maguire, Sigal, and Perrino (2005) investigated the type of verdict assigned by study participants after they read a 12-page summary of a case involving a battered woman who had shot and killed her husband.In particular, the researchers manipulated the race of the defendant (African American or Caucasian) and the type of abuse suffered (emotional or physical).The dependent variable was the number of guilty verdicts.What are the degrees of freedom associated with the chi-square analysis of these data?
A) 4
B) 3
C) 2
D) 1

The degrees of freedom for a chi-square analysis in this context are calculated based on the number of categories minus one for each variable, and since there are two variables (race with 2 categories and type of abuse with 2 categories), the formula is (2-1)*(2-1) = 1*1 = 1.
