Quantitative Research for the Qualitative Researcher is a concise, supplemental text that provides qualitatively oriented students and researchers with the requisite skills for conducting quantitative research. Throughout the book, authors Laura M. O'Dwyer and James A. Bernauer provide ample support and guidance to prepare readers both cognitively and attitudinally to conduct high quality research in the quantitative tradition. Highlighting the complementary nature of quantitative and qualitative research, they effectively explain the fundamental structure and purposes of design, measurement, and statistics within the framework of a research report, (including a dissertation). The text encourages the reader to see quantitative methodology for what it is, a process for systematically discovering new knowledge that can help describe, explain, and predict the world around us.

Minimizing Alternative Explanations for Research Findings: Internal Validity
Referring back to the axiom we stated in our Overview to Section II, when conducting research in the quantitative tradition, researchers aim to minimize probable alternative explanations for the results observed. In research parlance, minimizing alternative explanations by controlling nuisance variables that may be associated with the attributes or characteristics being studied is referred to as minimizing threats to the internal validity of a study. The concept of “internal validity” is somewhat parallel to the term credibility under the qualitative [Page 136]tradition, a connection we make in the section “Connections to Qualitative Research.” Campbell and Stanley ...
