Sampling Methods Report: Single-Sex Schools and Cooperation

This report details the sampling methods employed in a psychology research study investigating the impact of single-sex schools on inter-gender cooperation among university students. The study utilizes a purposive sampling technique, specifically typical case sampling, to select a sample of 200 participants. Inclusion criteria focus on students exclusively attending single-sex or multiple-sex schools, while exclusion criteria address participants with mixed school experiences. The report outlines the rationale for the sample size, inclusion/exclusion criteria, and the advantages and disadvantages of purposive sampling, including its cost-effectiveness and potential for bias. The research aims to test the hypothesis that single-sex school attendees have difficulty cooperating with the opposite gender, using data from multiple-sex school attendees as a control group. The report references key sources to support the chosen methodology and provides a comprehensive overview of the research design.
