Scientific research made accessible

This page aims to provide an overview of free solutions for data collection for research.

For online surveys or experiments, LimeSurvey is an extremely powerful, yet surprisingly userfriendly solution. It's originally an online survey system (i.e. for administering questionnaires), but with the recently introduced Expression Manager, advanced randomization and tailoring becomes very easy. Tailoring is possible using skip logic for entire groups of items, on item-level, or even by changing the wording of single items.
