The Program Evaluation KnowledgeBase : Element 2 : Activity 1 : Task 1: Define Data Requirements
Guideline: Data requirements drive off of the questions that the evaluation is addressing. When identifying data requirements be sure to address both qualitative and quantitative perspectives. Quantitative elements will be those that can be counted and measured. Qualitative elements will be those that describe how people feel about the program and its worth to them. In assessing the value of each data element give consideration to its importance within the overall evaluation and answering the questions being addressed.
This program evaluation guidance from the Centers for Disease Control suggests aspects of evidence gathering that typically affect perceptions of credibility. Being aware of these factors is important as the data requirements are defined.
