Exercise 6 “Speed Dating: Attractiveness”

Refer to the sample data for the given exercises in Section 13-2 on page 611. Use the Wilcoxon signed-ranks test to test the claim that the matched pairs have differences that come from a population with a median equal to zero. Use a 0.05 significance level.

Data From Exercise 6 Section 13-2:

Listed below are “attractiveness” ratings (1 = not attractive; 10 = extremely attractive) made by couples participating in a speed dating session. The listed ratings are from Data Set 18 “Speed Dating”. Use a 0.05 significance level to test the claim that there is a difference between female attractiveness ratings and male attractiveness ratings. 

Data Set 18: Speed Dating 

Data are from 199 dates (first five rows shown here). DEC BY FEM is decision (1 = yes) of female to date again, AGE FEM is age of female, LIKE BY FEM is “like” rating by female of male (scale of 1-10), ATTRACT BY FEM is “attractive” rating by female of male (scale of 1-10), ATTRIB BY FEM is sum of ratings of five attributes (sincerity, intelligence, fun, ambitious, shared interests) by female of male. Data for males use corresponding descriptors. Higher scale ratings correspond to more positive impressions.
