Question

A personal director at a large company would like to determine whether the company cafeteria is widely used by employees. She sits by the cafeteria entrance and counts how many employees enter. This study design would be considered:________.

Answer 1

observational study.

Explanation:

Observational study is a study where individuals are observed for a specific outcome.

Contrary to the experimental study, there is not an intervention done (no treatment), only the observed outcome is used for the analysis.

Here the director observes the personnel who uses the cafeteria, and tries to determine the proportion of the cafeteria usage.
