POL 51 Lecture Notes - Lecture 6: Confounding, Content Validity
Document Summary
Office hours moved to wednesday (12-2pm) just for next week. Evaluate the measure you proposed on monday using the criteria we covered in lecture. If unsure a single measure achieves 4 criteria (operationalizations are not observable, 1 question, etc. ) We can get closer to the true value. In reality, each survey question is its own measure. We use multiple measure to get a better overall measure of the construct of interest. Multiple measures also applies outside of survey research. Hypothesis: expects that linguistic differences between items compromise their cross-language validity (he expects them to be different between english speaking people and spanish speaking people) 4 agree-disagree questions about specific traits that an immigrant must hold in order to be considered part of the american society. (american identity = ) Goal: to determine if the items (each question) work the same for both groups. Would like the items to be invariant across groups.
