This DVD explores how the results of experimental research can be misleading due to problems with sample selection and assignment of participants to groups. It discusses the importance of using random sampling, looking at simple, stratified, and proportional random sampling, and emphasizes the need to look closely at the sample and population when drawing conclusions. The program also offers tips on assigning participants to research conditions.Contributors
