What type of data may be collected in a field experiment?

Field experiments are designed to investigate behaviors or phenomena in real-world settings while maintaining a degree of control over variables. One of the key advantages of conducting research in the field is the ability to gather rich and diverse types of data.

Qualitative data can provide in-depth insights into participants' thoughts, feelings, and motivations, which is often crucial for understanding complex human behaviors in context. Examples include interviews, open-ended survey responses, or observational notes where researchers describe interactions and social dynamics.

On the other hand, quantitative data can be collected through structured observations, surveys with fixed-response formats, or measurement instruments that yield numerical data. This type of data allows researchers to quantify behaviors, identify patterns, and perform statistical analyses.

By combining both qualitative and quantitative methods, field experiments enrich the analysis, providing a more comprehensive understanding of the phenomena under investigation. This approach capitalizes on the strengths of each type of data, allowing for triangulation and a more robust interpretation of results. Thus, the correct answer highlights the versatility of field experiments in utilizing multiple data types to enhance research findings.
