Question:
Reality TV and cosmetic surgery. Refer to the Body Image: An International Journal of Research (March 2010) study of the influence of reality TV shows on one’s desire to undergo cosmetic surgery, Exercise 12.17 (p. 728). Recall that psychologists modeled desire to have cosmetic surgery 1y2 as a function of gender 1x12, selfesteem 1x22, body satisfaction 1x32, and impression of reality TV 1x42. Suppose you want to determine which subset of these four independent variables is best for predicting one’s desire to have cosmetic surgery. Consequently, you will run a stepwise regression.
a. In step 1 of the stepwise regression, how many t-tests will be performed?
b. In step 2 of the stepwise regression, how many t-tests will be performed?
c. Access the data saved in the file and run the stepwise regression. Which independent variables comprise the best subset of variables for predicting one’s desire to have cosmetic surgery?
d. Do you recommend using the resulting stepwise regression model for predicting one’s desire to have cosmetic surgery or do you recommend further analysis? Explain your reasoning.
