Dropout rate is defined as the percentage of participants who start taking a study but do not complete it. Dropout rate is sometimes referred to as attrition rate, and is the opposite of completion rate (dropout rate = 100 – completion rate). On MTurk, completion rate is defined as the number of Workers who submit a HIT divided by the number of Workers who accept the HIT. Note that, for the definition of completion rate used here, Rejected Workers are counted as completes.
Users of Qualtrics and Google Forms have long enjoyed the ability to integrate dynamic secret codes for each participant in their TurkPrime study. Dynamic codes ensure that each MTurk worker participating in your study receives a unique code completely eliminating the possibility that workers share secret codes. In addition, with auto-approval enabled, those workers are automatically approved without any need for researchers to manually check the worker supplied secret codes and approve workers.
Now, TurkPrime users who host their studies on SurveyMonkey or SurveyGizmo can also use dynamic completion codes as follows:
Highlights We collected high quality data on MTurk when using TurkPrime’s IP address and Geocode-restricting tools. Using a novel format for our anchoring manipulation, we found that Turkers are highly...Read More >
