This reader is an adaptation of the fourth edition of Research Methods in Psychology by Jhangiani, Chiang, Cuttler & Leighton. It also adapts a chapter from Social Science Research: Principles, Methods and Practices, by Bhattatcherjee This work (and, for that matter, both books it adapts from) is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. The goal of this adaptation is to improve the fit of the material to the Research Skills pre-msc course, which focuses on business research rather than psychological research (though the disciplines share many similarities). To this end, this reader selects and adapts a set of relevant chapters from the original book. A more detailed list of changes can be found at the end of the book. This reader is a ‘living document’, in the sense that material is changed on an annual basis to improve this fit with the course it is associated with.
