“Are Women Really More Talkative Than Men?” is the title of a2007 article that appeared in the journal Science. In the article,Mehl and colleagues report the results of a study of 396 men andwomen. Each par-ticipant wore a microphone that recorded every wordhe or she uttered. The researchers counted the number of wordsuttered by men and women and compared them. The data below arefictional but they re-create the pattern that Mehl and colleaguesobserved:
Men: 16,345 17,222 15,646 14,889 16,701 Women: 17,345 15,59316,624 16,696 14,200
Conduct the appropriate t-test (independent or paired)to test the hypothesis that there is a difference in the number ofwords uttered by men versus women using a two-tailed ? = .05
Calculate r2 as a measure of effect size, and statewhether the effect is small, medium, or large.
Calculate the 99% confidence interval to determine whether ornot the result is significant at the
the ? = .01 level.
Report the your results in APA style as you would do in ajournal article.
