I have an ACBC task for one study, and a MaxDiff for another.
Two data quality indicators might be the following:
1) Speeder: Terminate a respondent if they have a very low total survey duration.
2) "Bad" responder: Terminate a respondent if they keep clicking the same option position repeatedly for x number of times in a set of choice task
How and what sort of code would I use to identify such respondents *during* their time in the study, so that they can be identified to not count towards my sample quota?
(Sorry, I'm still a beginner with Perl!)
