Final answer:
Double-barrelled questions should be avoided in surveys because they ask about two different things in one question, leading to confusion and complicating data analysis. Clear, concise, and focused questions are vital for collecting accurate survey responses.
Step-by-step explanation:
You should avoid using double-barrelled questions in a survey because they confuse respondents by asking about two different things. Double-barrelled questions make it more challenging for respondents to provide a clear and straightforward answer because they might have different responses to each part of the question. Additionally, this type of question can complicate the analysis of survey results since it is difficult to discern which part of the question the respondent is addressing in their answer.
Effective survey design is crucial for collecting valid and reliable data. To achieve this, questions must be clear, concise, and focused on a single issue. This ensures that respondents understand what is being asked and that their answers accurately reflect their opinions or behaviors.
Finally, survey designers should be cognizant of issues including question wording effects, interviewer bias, and response bias. These factors can influence the accuracy and validity of survey responses, making it essential to craft questions that minimize potential biases and errors.
