ABSTRACT
This chapter summarizes and integrates many of the concepts from the preceding chapters, and it expands our framework (presented briefly in chap. 19) to evaluate the quality of the design and analysis of a quantitative study (i.e., the research validity of a study). This framework uses several research validity rating scales adapted from those developed by Gliner and Morgan (2000) and Morgan, Gliner, and Harmon (1999). Here we discuss key concepts and present several figures and tables that provide the information needed to make a comprehensive evaluation of the research validity of an empirical quantitative study. The four studies described and evaluated briefly in chapters 1 and 19 are evaluated using this expanded framework in chapter 38.
