Public Program
Measurement and Data Collection
Data collection requires evaluators to consider a wide and diverse variety of data sources. These include both primary and secondary data sources. Data collection can significantly impact your evaluation project. Evaluators sometimes overlook problems where secondary data is involved and overlook the fact that data for comparison purposes can affect validity. The types of data in the Learning Resources are not meant to be exhaustive but are the most common types in program evaluation.
To prepare for this Discussion, choose one of the cases provided, review the specified Learning Resources, and complete the corresponding prompts.
Case 2
Barbara Geddes (1990) points out the pitfalls of selecting cases, units, or observations purely on the basis of the dependent variable.
Post by Day 3 a brief explanation of the relevance of Barbara Geddes’ argument for program evaluation. Then, explain when a scenario of choosing cases solely on the dependent variable might be permissible. Provide a rationale for your explanations.
Respond by Day 5 to two colleagues and explain in what ways you agree or disagree with the permissibility of the identified scenarios. Justify your reaction.
