Celebrated for its easy-to-grasp, user-oriented approach, this book puts research design into a practical context. Emphasizing that research must be internally valid, externally valid, and ethically conducted, Mitchell and Jolley show students how to use the theories of research methods, and give novices the practical advice they need to conduct successful research. Within this framework, the book encourages readers to value, create, and conduct ethical research projects. The authors introduce ethical issues in Chapter 1 and discuss ethics throughout the book.
