Evaluate Products ($0.50 for five minutes)(~ 5 minutes) - $0.50 +0.50 bonus Confirmed!

Generous

Unrated

Approved

$97.30 / hour

00:00:37 / completion time

Pros

Only 3 actual questions, besides demographics and simple attention checks.

Requestor sent bonus of $.50 based upon the consent form which stated $1.00 and HIT was set at $.50

Cons

The majority of the HIT is simple attention checks. Not really a con, as all of their HITs have the same easy anti-bot attention checks so you get used to them.

Product evaluation survey(~ 6 minutes) - $1.00

Generous

Unrated

Approved

$13.00 / hour

00:04:37 / completion time

Pros

Lmao. Anti vaxxers rating the pay as "low" because they had to watch a 4 minute FACTUAL video about vaccination.
Literally all this survey required was watch a 4 minute video and answer 3 questions. Super quick and easy.

Cons

No code.

Good

Unrated

Approved

$17.65 / hour

00:02:33 / completion time

Pros

omewhat quick.

Writing prompts, followed by a hypothetical and a single question. Demographics at the end.

Slim chance at a lottery style bonus.

Cons

Open ended writing at the start.

Return review stated 3 pages of writing. I only had 1 page with 2 short prompts. YMMV I guess.

Approval Tracking

Wage Aggregate Tracking

This is fairly straightforward: we take the completion time & the reward amount (where available) and calculate the average hourly rate for the task. We then apply that number to a simple range based on US minimum wage standards to color-code the data for easy to digest numerical data.

Color Pay Range (Hourly) Explanation
RED < $7.25 / hr Hourly averages below US Federal minimum wage
ORANGE $7.25 - $10.00 / hr Hourly averages between Federal & highest statewide (CA) minimum wages.
GREEN > $10.00 / hr Hourly averages above all US minimum wage standards

Reward Sentiment

Not all HITs are created equal. Sometimes an hourly wage doesn't convey the full story of a HIT's true worth, so we encourage workers to give their opinion on the overall pay of the task. Was it $8/hr to rate pictures of puppies? A worker could justifiably bump up the rating a bit for something so adorable. 10 hours locked in Inquisit? Even for $10/hr many workers would appreciate the heads up on such a task. The Pay Sentiment rating helps connect workers beyond the hard data.

Icon Rating Suggested Guidelines
Underpaid 1 / 5
  • Very low or no pay
  • Frustrating work experience
  • Inadequate instructions
Low 2 / 5
  • Below US min-wage ($7.25/hr)
  • No redeeming qualities to make up for pay
Fair 3 / 5
  • Minimum wages for task (consider SE taxes!)
  • Work experience offers nothing to tip the scales in a positive or negative direction
Good 4 / 5
  • Pay is above minimum wage, or compensates better than average for the level of effort required.
  • The overall work experience makes up for borderline wages
Generous 5 / 5
  • Pay is exceptional.
  • Interesting, engaging work or work environment
  • Concise instructions, well designed HIT.

Communication Ratings

Communication is an underrated aspect of mTurk. Clear, concise directions. A fast response to a clarification question or a resolution to a workflow suggestion can all be valuable aspects of interaction between Requesters & Workers and its worth keeping track of. Plus everyone enjoys the peace of mind knowing that if something does go wrong there will be an actual human getting back to you to solve the issue.

Icon Rating Suggested Guidelines
Unacceptable 1 / 5
  • No response at all
  • Rude response without a resolution
Poor 2 / 5
  • Responsive, but unhelpful
  • Required IRB or extra intervention
Acceptable 3 / 5
  • Responded in a reasonable timeframe
  • Resolves issues to a minimum level of satisfaction.
Good 4 / 5
  • Prompt Response
  • Positive resolution
Excellent 5 / 5
  • Prompt response time
  • Friendly & Professional
  • Helpful / Solved Issues
  • Interacts within the community

Approval Time Tracking

This rating is strictly for approval times. Let's face it, no one wants to mix approval time ratings with how fast a Requester rejects a HIT, so we've saved rejection flags for another category. This provides a more straightforward way to know about how long your HIT might sit pending before paying out. The default auto-approval for most MTurk tasks is 3 days, the maximum is 30 days. We've tried to base our ratings around those data-points.

Icon Rating Approval Time
Very Slow 1 / 5 Over 2 weeks
Slow 2 / 5 ~1 - 2 Weeks
Average 3 / 5 ~3 - 7 Days
Fast 4 / 5 ~1 - 3 Days
Very Fast 5 / 5 ~24 hours or less
