Gathering Quantitative Primary Data
In this video, we focus on how health educators gather quantitative primary data as part of the needs assessment process. Quantitative data gives you the numbers — the measurable, objective evidence that drives decision-making in health education planning. Understanding how to collect it properly is a key competency within Area I and a frequent topic on both the CHES and MCHES exams.
We walk through the most common methods for collecting quantitative primary data, discuss when each method is most appropriate, and connect it all back to how NCHEC frames these concepts in exam scenarios.
