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.

Chapter Outline

  • What Is Measurement?
  • Measurement Scales
  • Common Ways to Collect Data
  • Linking Measurement Instruments to the Research Questions and Hypotheses

When conducting research in the quantitative tradition, researchers must select appropriate measurement instruments for collecting the data that will be used to address the research questions posed. Instruments are used to measure the attributes of individuals or groups, and the scores on the instrument provide the data for answering the research questions and testing the research hypotheses. Similar to the variety of instruments we use to measure physical attributes (e.g., weighing scales for measuring weight, sphygmomanometers for measuring blood pressure, spectrometers for measuring the wavelength of light, etc.), there are ...
