Researchers have often to do with surveys, questionnaires and other inquiries. Deploying a survey can be easier than expected with LimeSurvey (formerly PhPSurveyor).
LimeSurvey is a PHP web application (PHP & MySQL are needed for installation) for publishing online multi-question and multi-lingual surveys. It comes with a lot of great features (one of the most useful: conditional questions i.e. questions that appear only if the user give a specific answer to a previous question).
Basic statistical analysis and graphs are avalaible, as well as multiple formats export of survey results.
I’ve already used it in a couple of situations, with complete satisfaction.
