What is a questionnaire?

A questionnaire is best described as a survey that consists of a series of questions designed to gather information from respondents. This method is particularly effective for collecting primary data, as it allows researchers to directly engage with individuals and obtain their responses on various topics. Questionnaires can be used to assess attitudes, opinions, behaviors, and demographic information, making them versatile tools in both social research and market studies.

The format of a questionnaire typically prioritizes clarity and ease of completion, enabling respondents to provide information quickly and accurately. This aspect is essential for ensuring a high response rate and reliable data collection. The structured nature of questionnaires often leads to quantitative data, facilitating statistical analysis later on.

In contrast to the other options, a questionnaire is not limited to collecting secondary data, which involves analyzing information that has already been gathered by someone else. It's distinct from a research method that solely focuses on statistical analysis without direct interaction with subjects. Additionally, it differs significantly from observational research techniques, which involve watching subjects in their natural environment without their direct input or feedback regarding community or family-related issues.
