Comparability Effects

Show Summary Details


Comparability issues arise when different surveys are compared. Surveys taken by different organizations, in different countries, and/or at different times are often compared, but the differences that are found are not necessarily meaningful. The first section of this chapter focuses on the meaning of equivalence between surveys, after which the second section briefly examines three related comparability issues: “house effects,” cross-cultural differences, and over-time differences. House effects refers to the differences that different survey organizations sometimes obtain even when they ask the same question to the same population. Cross-cultural differences are the factors that preclude total equivalence when the same question is asked in multiple countries. Over-time differences relate to changes in the meaning of survey questions over time.
