Almost every other societal studies such as for instance Qualtrics may store the new paradata for free, yet , for a charge allow boffins by yourself to keep and you can access this type of data. 42 Thus, experts and you may IRBs need to be mindful of which survey solution is actually always stop breaches when you look at the investigation safety and security.
