The positioning of the dropdown clearly has a lot of influence on the results. People are horrible random number generators! In this case, people are unlikely to choose the ends (1/9) or the center (5) leading to a bimodal distribution with two modes at 4 and 7.
Note however that different types of input systems were used. Refreshes show the following different types:
* A slider that need to be dragged to choose a value.
* A list of numbers shown with highlighting on hover.
* An input cursor that on hover changes to a list of numbers (within a curved border this time).
* A text field (enclosed in a circular border), allowing manual input.
I'm quite interested in how results varied depending upon input type (possibly more interesting than seeing how they vary by referrer).
