While it is always important to ask clear and unambiguous questions regardless of the method that you use, it is especially important to avoid confusion when conducting surveys. why?

A survey is a group of questions aimed at getting information on the respondents.

If a person does not understand your question, or does not do so in the specific way that is necessary for your research, you could end up measuring a completely different variable and your research would lack internal validity.
