A researcher repeats Vohs and Schooler's (2008) study and randomly allocates 30 undergraduates to the two passage conditions. By chance, one condition ends up with more people who play a lot of computer games.
Explain what random allocation does and does not achieve in this study.
36 exam-style questions on Edexcel GCSE Psychology 7.2 Studies, covering 7.2.1 Vohs and Schooler (2008) and 7.2.2 Van Houtte and Jarvis (1995). Each one has a worked solution and a mark scheme showing where the marks go.
