Mechanical Turk instructions

Regardless of which survey site you use, the survey must generate a unique ID for each respondent, show that ID to the respondent at the end of the survey so that they can enter it back on the Mechanical Turk website. Before paying, you can quickly check whether the unique IDs are correct (or even just look correct, e.g., right length, not repeated).

Here is an example of the HTML code for the Mechanical Turk site (regardless where you host the survey). Enter this information in the design layout tab (make sure you click the "Edit HTML source button").

Before you paste in the text below, clear the box of any other HTML code.

<p>Answer questions about movie stars and politics. Usually takes less than 3.5 minutes.</p>

<p>You can find the survey here:</p>

<p><a href="http://www.surveygizmo.com/s/149195/2gfcu"

<p>At the end of the survey, you'll find a code. To get paid, please

enter the code below:</p>

<p><textarea rows="3" cols="80" name="answer"></textarea></p>

As you can see when you switch out of "edit HTML" mode, this creates a box where people can enter the unique IDs. Mechanical Turk automatically stores whatever people paste into this box and associates it with the unique mechanical Turk ID of each participant.
