A unit commander is interested in understanding members' knowledge of primary prevention. What is an example of a quantitative data method that could be used?

Surveys are an effective quantitative data method for gauging members' knowledge of primary prevention. They allow for the collection of numerical data through structured questions that can be easily quantified and analyzed statistically. This method enables the commander to gather information from a larger sample size, providing a broad perspective on the members' understanding.

Surveys can also include rating scales or multiple-choice questions, making it straightforward to measure levels of knowledge and identify patterns in responses. The insights gained from surveys can inform decisions and strategies related to training and intervention.

In contrast, the other methods mentioned, such as interviews, observation, and case studies, primarily yield qualitative data. While these approaches offer valuable insights and context, they do not provide the same level of statistical analysis and broad applicability that quantitative surveys can achieve. This distinction highlights why surveys are particularly suited for assessing knowledge levels within a unit.
