What are the Advantages and disadvantages of a questionnaire as method of collecting primary data?

Advantages of using a questionnaire for collecting primary data include the ability to gather information from a large number of respondents efficiently and cost-effectively, as well as the ease of data analysis due to standardized responses. However, disadvantages include the potential for low response rates, which can lead to biased results, and the limitation of capturing nuanced responses, as questionnaires may not allow for in-depth exploration of complex issues. Additionally, poorly designed questions can result in misunderstandings and inaccurate data.
