It enables researchers to passively collect different kinds of client-side paradata, such as response times and scrolling events – irrespective of the Internet browser and operating system used – to investigate respondents’ completion behavior with respect to web surveys. Paradata are collected at the page-level and are stored together with the actual survey data (i.e., respondents’ answers) in the same dataset.
