In this study researchers were interested in gender differences in willingness to engage in casual sex. Both males and females were approached by opposite sex confederates and asked one of the three questions: “I have been noticing you around campus. I find you to be very attractive.” Then the confederate asked one of these three questions: “Would you go out with me tonight?” “Would you come over to my apartment tonight?”
“Wouldyou go to bed with me tonight?” The type of question was randomly determined for each request. Test for a relationship between gender and compliance with each request. Interpret your findings. The results for the first two questions are as follows: DateYesNoMale142Female610There are four total expected values:Q7:What are the expectedvalues for ‘male-yes’ and ‘female-yes’ (they should be the same)?Q8:What are the expectedvalues for ‘male-no’ and ‘female-no’ (they should be the same)?Q9:What is the calculated chi-squared value?Q10:Using a critical value of 3.84, was there a significant relationship between gender and compliance?A.YesB.NoApartmentYesNoMale88Female610There are four total expected values:Q11:What are the expectedvalues for ‘male-yes’ and ‘female-yes’ (they should be the same)?Q12:What are the expectedvalues for ‘male-no’ and ‘female-no’ (they should be the same)?Q13:What is the calculated chi-squared value?Q14:Using a critical value of 3.84, was there a significant relationship between gender and compliance?
