What are some concerns and considerations when designing a questionnaire?
First of all, you don't want to be biased- or have hidden biased. This is one issue that should be considered. Sometimes, questionnaires can have hidden bias in the questions that are asked or the way they are asked.
Reply:simplicity. Make the questions short. Allow for short answers. Too much text is a turn off.
Reply:The prime concern is whether or not your respondants can understand your question. So simplicity and clarity in the design of questions is imperative.


Then you have to check for bias -- make sure your question isn't of the 'did you stop smoking because it was a vile disgusting habit?' type, or the non-sequetir of the 'have you stopped beating your wife' genre. In other words, your question must be phrased so it doesn't invite a particular answer, but rather is open enough that the respondant can be either for or against without feeling intimidated.


There should also be control questions. These are questions that you can predict the asnwers for, just to make sure someone isn't joking around with their responses. And then you can add verifying questions. Phrase the same question two or three different ways to see if you get the same answer each time.


Hope this helps.
Reply:1. Avoid biased questions.


2. Sometimes people answering questionnaires get tired of the questions and just fill in answers.


3. Sometimes people don't take the questionnaires seriously.


4. Make sure your population sample is either random or representative, else your questionnaire won't mean a thing.
