Task 2: Both Ozzy Osbourne and Judas priest have been accused of putting backward masked messages on their albums that sublimially influence poor unsuspecting teenagers into doing things like blowing their heads off with shotguns. A psychologist was interested in whether backward masked messages could have an effect. He created a version of Britney Spears's Baby one more time' that contained the masked message 'deliver your sould to the dark lord' repeated in the chorus. He took this version, and the original, and played one version (randomly) to a group of 32 people, Six months later he played them whatever version they hadn't heard the time before. So each person heard both the original and the version with the masked message, but at different points in time. The psychologist measured the number of goats that were sacrificed in the week after listening to each vversion. Test the hypothesis that the backward message would lead to more goats being sacrificed using Wilcoxon signed-rank test (DarkLord.sav)

Task 8: Statistics and maths anxiety are common and affect people's performance on maths and stats assignments; women, in particular, can lack confidence in mathematics (Field, 2010). Zhang, Schmader, & Hall, (2013) did and intriguing study, in which students completed a maths test in which some put their own name onthe test booklet, wheares others were given a booklet that already had either a male of female name on it. Participants in the latter two conditions were told that they would use this other person's name for the purpose of the test. Women who completed the test using different name performed better that those who completed the test using own name. (There were no such effects for men.) The data below are a random subsmaple of Zhang et al.'s data. Enter them into SPSS and save the file as Zhang (2013) subsample.sav.
