Fundamentals of Research on Culture and Psychology [PDF ebook] 
Theory and Methods

This unique text covers the core research methods and the philosophical assumptions that underlie various strategies, designs, and methodologies used when researching cultural issues. It teaches readers why and for what purpose one conducts research on cultural issues so as to give them a better sense of the thinking that should happen before they go out and collect data. More than a 'methods text’, it is about all the steps that go into doing cross-cultural research. It discusses how to select the most appropriate methods for data analysis and which approach to use, and details quantitative, qualitative, and mixed methods for experimental lab studies and ethnographic field work.
