How does a survey differ from an interview in data collection?

Surveys typically use standardized questions, which means that each participant responds to the same set of questions in a consistent format. This standardization allows for easier analysis and comparison of responses across a larger sample size. The fixed structure of surveys limits the variability of responses, making it simpler to quantify data and identify patterns.

In contrast, interviews are characterized by their flexibility, allowing researchers to adapt questions based on the conversation that unfolds. This method can lead to deeper insights and a richer understanding of the participants' perspectives, as interviewers can probe further into responses and clarify any uncertainties. This flexibility often results in qualitative data, providing nuanced insights that standardized survey questions might not capture.

By emphasizing the structured nature of surveys and the conversational approach of interviews, the correct answer highlights a fundamental distinction in the methodologies of data collection in research. This understanding is crucial for determining the appropriate method based on the research goals.
