How you design a survey and its questions will directly impact on your success. A survey can include any number and type of questions, and more complicated questions should appear only once users are comfortable with the survey.
Be careful that you do not introduce bias when creating questions by asking leading questions.
Example:
Incorrect:We have recently introduced new features on the website to become a first class web destination. What are your thoughts on the new site?
Replace with:What are your thoughts on the changes to the website?
In general, you will also find that you get more accurate answers when phrasing questions in the past tense than in the continuous tense.
Example:
Incorrect: How many times a week do you buy take-away food?
Replace with: In the past month, how many times did you buy take-away food?
Questions in the survey should be brief, easy to understand and easy to answer.
