Sadly, bad quality responses do enter our Surveys. Be it boredom, or loss of interest, or straight out “I’m only doing this to get a couple of bucks”, it does happen. On top of that, there are malicious automated bots which will randomly answer the questions, again, purely for a small financial gain.
It is virtually impossible to stop this from happening, but it is possible to “clean” the final data set by removing any bad quality data. This is done by Researchers after all required responses have been gathered. If an entry is ‘suspicious’ it is removed (‘rejected’) and the individual receives no payment for their participation.
