Task 3: One of my pet hates is ‘pop psychology’ books. They usually spout nonsense that is unsubstantiated by science and give psychology a very bad name. As part of my plan to rid the world of popular psychology I did a little experiment. I took two groups of people who were in relationships and randomly assigned them to one of two conditions. One group read the famous popular psychology book Women are from Bras and men are from Penis, whereas another group read Marie Claire. I tested only 10 people in each of these groups, and the dependent variable was an objective measure of their happiness with their relationship after reading the book. The data are in the file Penis.sav. Analyse them with the appropriate t-test. ①
