Warner, R. M. (2013). Applied statistics: From bivariate through multivariate techniques (2nd ed.). Thousand Oaks, CA: SAGE Publications.

  • Chapter 21, “Reliability, Validity, and Multiple-Item Scales” (pp. 901–952)

    This chapter provides an important nugget of wisdom: The analyses you explored in previous weeks will yield meaningful results only if you have a well-specified model and if all the measurements for the variables are reliable and valid. This chapter outlines reliability, validity, and multiple-item scales, which should be acknowledged when evaluating the quality of measurements.
