MicroBatch is now a Pro Feature

TurkPrime is announcing a change in our pricing for the MicroBatch feature. MicroBatch is now included as a Pro feature, with a fee of 2 cents + 5% per complete. This will also provide users with access to all other pro features, with no additional charge. This change is necessary so that we can continue to provide the highest quality service and tools that our users expect.

To explain the new pricing structure further, see the following example (the part highlighted in blue reflects the recent change):

Study Example: # of HITs: 100

Payment per HIT: $1

Without MicroBatch: Total Study Cost = $140 With MicroBatch: Total Study Cost = $127 Payment to Workers: $100 Payment to Workers = $100 MTurk Fees (40%) = $40 MTurk Fees (20%) = $20 TurkPrime Fees (0%) = $0 TurkPrime Fees (2 cents + 5% per complete) = $7 Savings of 13%

Since its inception 3 years ago, TurkPrime has been dedicated to enhancing the quality and usability of online research with the goal of empowering researchers. The Team at TurkPrime remains committed to this mission. As more researchers come to use our platform and the online sampling world continues to evolve, we have taken on more staff, so that we can continue to provide individualized customer support to each of our users, and develop new tools to expand and improve functionality.

We greatly appreciate our relationship with our users, and know that this change will allow us to continue providing high quality service and equipping the research community with the tools and features they need. We also know that for some users this change was unexpected.  If you have a funded grant with funds allocated to participant collection based on our previous pricing, please contact us so that we can honor our previous pricing. We look forward to your feedback, and to assisting you in getting the most out of your research and TurkPrime.

HyperBatch - Run Batched HITs at Hyper Speeds

HyperBatch Feature 

You can now run your Amazon Mechanical Turk studies at Hyper speeds. We worked hard to make the experience identical to our classic MicroBatch option so that you simply launch your study and TurkPrime does all the heavy lifting for you.

How it works

When you launch a HyperBatch study with 100 participants, for example, your study appears on TurkPrime exactly as a standard study. However, the study, in fact, is broken down into multiple HITs with 9 or less participants. When you pause or change a study, all of the HITs associated with your study are paused or updated, respectively.

Workers who completed one HIT in the study are disabled from taking additional HITs. TurkPrime automatically assigns the Worker a Qualification that prevents them from taking your study twice.

All existing features such as secret code, include / exclude / groups etc work exactly as you expect them to.

Our Micro-batching Feature will Improve the Quality of Your Data

MicroBatch


We have deployed a micro-batching feature which allows Requesters to break up their studies into smaller segments, and to include time intervals between the segments. We developed this feature to increase sample representation. This feature can also save 50% in MTurk fees.


The Problem

Here is why this feature is important for data quality. If a Requester launches a study on Monday afternoon, there may be a bias in the sample toward people who are not working on a weekday (unemployed, stay at home parents etc.)
