HLTH 200 Study Guide - Midterm Guide: Convergent Validity, Discriminant Validity, Construct Validity
Document Summary
Be able to assess the quality of a measurement tool. Understand the theory of what constitutes good measure. Understand how to construct questions used for survey research. Know the steps involved in conducting a community survey. Explain the difference between multidimensional and uni-dimensional scaling. Learn when each type of index or scale is most appropriate. Describe qualitative data and how it differs and complements quantitative data. Explain standards for judging the validity of qualitative measurement. Measurement is the process of observing and recording the observations that are collected as a part of a research effort. Construct validity versus measurement validity: measurement validity is an offspring of construct validity. Construct validity focuses on maximizing concordance between variables (independent and dependent), or the approximate truth of the conclusion that your measure accurately reflects its constructs. In other words, it is the degree to which inferences can legitimately be made from the operationalizations to the constructs in which they are based.
