Data Collection
Do you remember the difference between quantitative and qualitative data?
Take a moment to review the difference between quantitative and qualitative data:
- Quantitative data is information in numeric form (i.e., things that can be counted, measured, or compared on a numerical scale)
- Qualitative data is descriptive (i.e., things that can be observed, but not measured)
Both types of data provide evidence to support programs and policies that can improve individual and population health.
After completing this section, you will be able to:
- List five data collection methods for program evaluation
- Design a basic survey questionnaire
- List two methods of selecting a survey sample
- Describe key components in planning and conducting interviews and focus groups
