This enables us to specify the maximum allowed deviation/exceeding of the average survey duration (median), e.g. 70%.
Example: The median is 6 minutes. Using a deviation acceptance of 70%, participants who are more than 30% quicker than the median time are disqualified, i.e. quicker than 1 min 48 secs.
The median is not a fixed value and can be constantly adjusted to the participants during the survey.
3. Control questions
“Incorrect answering” of a control question (e.g. Note: This is a control line. Select “6 – disagree completely”) leads to a negative point. Negative points can also be awarded for open entries, for example if a minimum number of characters have not been entered in a text field.
If a control question is answered incorrectly, an instruction to read the question carefully follows.
If multiple control questions are answered unsatisfactorily, the participant accumulates a correspondingly high number of negative points during the survey. The number of negative points that disqualify a participant in the current survey can be individually set.
This tests whether the respondent assigns the same value to every statement on selected rating questions. The rating questions to be checked can be individually determined.
In addition, the maximum number of identical rating answers allowed can be set as a percentage, e.g. 75%.
