What are the qualities of a good questionnaire ? |
|
Answer» Need to know what needs to be measured – Having a clear picture and understanding of what data needs to be collected contributes to the quality of data collection. Should know how to word/frame question and words should be neutral and should not be leading – Whatever your opinion may be, own opinion should never be reflected in the questions. This is done both intentionally and unintentionally but should be taken care of. Emphasis on right word/phrase should be kept in mind – The language should be clear so that the required data can be received. This also makes the question and the requirement of survey easy to understand and thus help in getting a better response and answer. Define and qualify terms – This is most essential when a technical survey or a field specific survey is being done. If you think that the audience being surveyed might not know about some terms than they must be defined to get any proper response. This will increase the quality and decrease the bounce rate or number of questions which were left unanswered. Avoid double negatives or more than 1 negative word in question – Use of negative word has a psychological effect and can influence the answer. Sufficient or adequate alternatives should be provided – Available options should have the most expected answers. |
