Identify Biased Text - $1.00 +0.25 bonus Unpaid Bonus!

Low

Unacceptable

Approved

$9.45 / hour

00:07:56 / completion time

Pros

Read instructions - work through 20 tasks answer one question on each - earn 5c for each one answered correctly if your accuracy exceeds 65% (so I got 90% so my bonus was 5x5c) - answer 12 social/political questions - could be done faster - same day approval

Cons

04.05.2022 - sent a message chasing the bonus I have no record of ever receiving it.
04.25.2022 - NEVER RECIEVED THE BONUS - yes it was for a minimal amount its the principal of being told you will be paid something and then nothing!

Advice to Requester

If you state that you will pay a bonus, no matter how much it is then you should pay it. Also you should check this system for any messages as I am assuming you don't. For all I know you probably won't read this!

Can I Eat This Mushroom? - $1.80

Underpaid

Unrated

Approved

$4.88 / hour

00:22:09 / completion time

Pros

Cons

I would suggest staying away from this HIT, I am not getting a bonus even though I should be because I failed the attention checks....I just finished this and I know what the attention checks were...oh pick the third choice from the left...right lets make the attention checks as ambiguous as possible so that when they mess it up we don't have to give them their bonus....because please tell me what other requester doesn't care if you "fail an attention check" when it comes to paying you for doing the hit, just not the bonus....how does that make sense, oh right, cuz the whole thing is a scam, got it.

Identifying Nutrition Components in Meals and Get Up to $3.50! - $0.25 +1.75 bonus Confirmed!

Low

Unrated

Approved

$4.76 / hour

00:25:12 / completion time

Pros

2 follow ups, but pay is low, so not sure that is a pro...

Cons

Too many videos to watch and quizzes to do to make this a good hourly. There was a practice session that you didn't have to do. I went through it, which added on to my time.
Edit - I was not able to accept either of the followups. It took a week for them to respond to my email. They looked in to the issue and said due to an error on their part they allowed to many people in to the study and only the first 700 could continue. They also told me I would be paid my bonus when the study was finished but I have yet to receive it.

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
