In this fascinating, brief book, Matsumoto takes a look at the often very dramatic effect culture has on the ways that psychologists conduct research and analyze data. He covers issues that are extensions of the general issues in research methodology and statistics, as well as issues truly unique to research across cultures, such as problems due to translation. The issues discussed are applicable not only to research conducted in different countries, but also to research that compares people to different ethnicities and races, both within and across countries, and across gender.
