A questionnaire is a research instrument consisting of a series of questions and other prompts for the purpose of gathering information from respondents. Although they are often designed for statistical analysis of the responses, this is not always the case. The questionnaire was invented by Sir Francis Galton. The aim of a questionnaire is to gather information for purposes of research for market surveys, analysis or even to corroborate other research findings. They are one of the cheapest and most feasible ways of gathering data. It is important to remember that for any questionnaire to be really effective it has to be designed well.
A sample questionnaire can help you formulate a good questionnaire. The standard questionnaire design is a set of questions with fixed alternatives. These alternatives could be dichotomous (having only two options e.g. yes/no), multiple options or rank scaling, etc. All the readers need to do is tick the most appropriate answer according to them. Any questionnaire, be it a health questionnaire or a product questionnaire, must have a specific objective. Generally questionnaires have subjective/objective and qualitative/quantitative options depending on their type. A customer satisfaction questionnaire may have more qualitative/subjective parameters for gauging.

Basic rules for questionnaire item construction
Use statements which are interpreted in the same way by members of different subpopulations of the population of interest. Use statements where persons that have different opinions or traits will give different answers. Think of having an “open” answer category after a list of possible answers. Use only one aspect of the construct you are interested in per item. Use positive statements and avoid negatives or double negatives. Do not make assumptions about the respondent.
Use clear and comprehensible wording, easily understandable for all educational levels Use correct spelling, grammar and punctuation.
Avoid items that contain more than one question per item (e.g. Do you like strawberries and potatoes?). Question should not be biased or even leading the participant towards an answer.
The responses are gathered in a standardized way, so questionnaires are more objective, certainly more so than interviews.
Generally it is relatively quick to collect information using a questionnaire. However in some situations they can take a long time not only to design but also to apply and analyze (see disadvantages for more information).
Potentially information can be collected from a large portion of a group. This potential is not often realized, as returns from questionnaires are usually low. However return rates can be dramatically improved if the questionnaire is delivered and responded to in class time.
Large amounts of information can be collected from a large number of people in a short period of time and in a relatively cost effective way
Can be carried out by the researcher or by any number of people with limited affect to its validity and reliability
The results of the questionnaires can usually be quickly and easily quantified by either a researcher or through the use of a software package
When data has been quantified, it can be used to compare and contrast other research and may be used to measure change
Positivists believe that quantitative data can be used to create new theories and / or test existing hypotheses
Is argued to be inadequate to understand some forms of information – i.e. changes of emotions, behaviour, feelings etc.
Phenomenologist’s state that quantitative research is simply an artificial creation by the researcher, as it is asking only a limited amount of information without explanation.
There is no way to tell how truthful a respondent is being.
There is no way of telling how much thought a respondent has put in.
The respondent may be forgetful or not thinking within the full context of the situation.
People may read differently into each question and therefore reply based on their own interpretation of the question – i.e. what is ‘good’ to someone may be ‘poor’ to someone else, therefore there is a level of subjectivity that is not acknowledged.
There is a level of researcher imposition, meaning that when developing the questionnaire, the researcher is making their own decisions and assumptions as to what is and is not important…therefore they may be missing something that is of importance.
