Social Research Methods MAN-10 Erlan Bakiev, Ph. D. Chapter 7: Qualitative and Quantitative Measurement

Need for Measurement Quantitative measurement Qualitative measurement

Qualitative vs. Quantitative Measurement Timing Type of Data Construct-to-data linkage

Measurement Process Conceptualization Operationalization Conceptual definition Operationalization Operational definition

Quantitative Measurement Rules of correspondence Conceptual hypothesis Empirical hypothesis

Qualitative Measurement Conceptualization Operationalization Casing

Reliability and Validity Quantitative Research Measurement reliability Stability reliability Representative reliability Equivalence reliability

Reliability and Validity Quantitative Research Improve Reliability Conceptualization Increase level of measurement Multiple indicators Pretest, pilot studies, and replication

Reliability and Validity Quantitative Research Measurement Validity Face validity Content validity Criterion validity Concurrent validity Predictive validity Construct validity Convergent validity Discriminant validity

Relationship between Reliability and Validity

Other Uses of the Terms: Reliability and Validity Internal validity External validity Statistical validity

Quantitative Measurement Levels of Measurement Continuous variables Discrete variables

Quantitative Measurement Levels of Measurement

Quantitative Measurement Levels of Measurement

Quantitative Measurement Principles of Good Measurement Mutually exclusive attributes Exhaustive attributes Unidimensionality

Quantitative Measurement Scales and Indexes

Quantitative Measurement Index Construction Purpose Weighting Rates and Standardization Missing Data Eliminate cases w/ missing data Substitute average Substitute w/ nonquantitative info. Insert random value

Quantitative Measurement Scale Construction Purpose Logic of scaling Commonly use scales Likert scale Thurstone scale Bogardus social distance scale Semantic Differential Guttman scaling

Likert Scale

Thurstone Scale

Bogardus Social Distance Scale

Semantic Differential

Guttman Scaling
