Verified US Region Targeting

Posted by TurkPrime on Dec 2, 2016 1:22:00 PM

Problem

Many researchers wish to target participants from specific states or regions of the United States like the Northeast or the West. The problem they often encounter is that using MTurk's Geographic Qualification to specify a particular state is often not adequate to ensure participants actually reside in the specified state.

Dynamic Secret Completion Codes for SurveyMonkey and SurveyGizmo

Posted by TurkPrime on Dec 2, 2016 1:04:00 PM

What is the completion rate and dropout rate?

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.

How to Create a Universal Exclude Worker List

Posted by Jonathan Robinson on Sep 9, 2016 10:41:00 AM

Problem: 

Requesters may observe that some workers, even those with high Approval ratings, may not perform to their expectations on a study. Sometimes this may result in rejecting their work which affects the Worker approval rating. But, often the work is not acceptable for research but is not worthy of rejection, or, it may simply be the policy of the research lab to approve all assignments for IRB or some ethical standard they may follow.

Reusable Include and Exclude Groups

Posted by Jonathan Robinson on Sep 9, 2016 10:36:00 AM

Problem:

You are running a longitudinal study and have identified 1000 workers who you want to allow to take your second phase studies. How do you easily group those workers for easy access.

Or you want to exclude certain workers from taking a number of your studies and wish to group them for easy exclusion in future studies. How can you do that?

New Safety Feature: Assignment Rejections are not Automated and Require Manual User Action

Posted by Jonathan Robinson on Feb 19, 2016 10:39:00 AM

Many researchers set up their studies to use the TurkPrime AutoApprove feature so that they do not need to manually approve worker assignments based on the secret code that workers enter. On occasion, a researcher may set up his study incorrectly which results in many worker assignments getting automatically rejected. This was a significant cause for distress among the Mechanical Turk workers who received rejections for their work which then went unpaid and also lowered their MTurk approval rating. This was also a sore point for TurkPrimeresearcherswho had to deal with upset workers and correspond with them, and often reverse their rejections.

Anonymize Mechanical Turk Worker IDs

Posted by Jonathan Robinson on Jan 18, 2016 6:32:00 PM

We recently launched a ground-breaking feature that helps protect Mechanical Turk worker identities. It has been reported in the literature that Mechanical Turk Worker IDs can be used to identify the worker. This is because Amazon uses the same value for both the Worker ID on Mechanical Turk and elsewhere on Amazon properties like Amazon.com product reviews.
