Step-by-step explanation:
The primary data collection method exemplified by constructing see-through mirrors in a retail store to record consumers' actions is disguised observation and natural setting. Disguised observation involves observing people without their knowledge, while a natural setting refers to observing behavior in a real-life environment as opposed to a controlled setting. This method allows researchers to collect data on consumer behavior in an authentic setting without influencing their actions or responses.
