I'm new to MTurk and I have a large data collection task related to financial accounting data. I've tried to give clear explanations as well as setting up a help website with annotated examples. (The task is typing in earnings per share and adjusted earnings per share from provided tables.) I have about 18,000 tables to be examined and I'm trying to find the best way to get things set up in MTurk. I'm currently trying a small group of about 250 tables but I have the feeling that I've priced them too low. What's the best way to get feedback from workers on the appropriate price and how to improve the instructions/design of the task?
