How do surveys differ from interviews in data collection?

Surveys are characterized by the use of standardized questionnaires, which ensure that every participant responds to the same set of questions in the same format. This uniformity allows for easier comparison and statistical analysis of data across a larger group. In contrast, interviews tend to be less structured, allowing interviewers to adapt questions based on the flow of conversation and delve deeper into specific areas of interest. This flexibility can lead to more detailed qualitative insights from individual participants.

The other options do not accurately describe the differentiation between surveys and interviews. For instance, surveys are not limited to individual responses; they can indeed be administered to both individuals and groups but typically focus on gathering responses from individual participants. Surveys can also include qualitative questions, and while they may provide general insights, they are primarily used for quantitative analysis of data. Interviews primarily gather qualitative data, focusing on in-depth understanding rather than strictly adhering to statistical approaches.
