Part 1: Identifying the Unit of Analysis: Ecologic versus Cross-Sectional Studies
All of the study descriptions in Part 1 pertain to either ecologic or cross-sectional studies. For each one, first name the unit of analysis (1 point each). If it is a mixed ecologic study, with two different units of analysis, list both. Then identify the study design: ecologic or cross-sectional (1 point each).
Examples:
1. The level of unemployment was used as a measure of economic distress in Germany. Researchers examined the association between economic distress and general anxiety syndrome across states in Germany.
Unit of Analysis: the state (It is a sample of German states.)
Study Design: Ecologic
2. A survey was conducted in which the height, weight, level of alcohol consumption, and blood pressure in a sample of men and women aged 30-59 were measured.
Unit of Analysis: the individual man or woman (It is a sample of individual men and women.)
Study Design: Cross-sectional
