How can questionnaires help me do my research?

The biggest single advantage is that a usability questionnaire gives you feedback from the point of view of the user. If the questionnaire is reliable, and you have used it according to the instructions, then this feedback is a trustworthy sample of what you (will) get from your whole user population.





Another big advantage is that measures gained from a questionnaire are to a large extent, independent of the system, users, or tasks to which the questionnaire was applied. You could therefore compare the perceived usability of a word processor with an electronic mailing system,


the ease of use of a database as seen by a novice and an expert user,


the ease with which you can do graphs and statistical computations on a spreadsheet.





Additional advantages are that questionnaires are usually quick and therefore cost effective to administer and to score and that you can gather a lot of data using questionnaires as surveys. And of course, questionnaire data can be used as a reliable basis for comparison or for demonstrating that quantitative targets in usability have been met.





Good luck... this website should help.
