Jeremy Singer-Vine at Slate magazine has posted his own analysis based on Test Pilot’s Week-in-the-Life dataset!

He looked at tab use, and while his general conclusions are similar to what we found from the earlier tab study, his chart of tab use by demographics shows something interesting I’ve never seen before:

Jeremy rightly points out that the data behind this graph may not be the most reliable, due to the severe undersampling of women in the Test Pilot user base, as well as the fact that most Test Pilot users who submitted data did not fill out the optional demographic survey. It should be taken with a large grain of salt. Still, by suggesting that there might be significant differences in tab use patterns by age and sex, it points to what might be an interesting area for future experimentation.

This might be a good time to remind you that the deadline of the Open Data Competition is December 17. So there’s still time to do a visualization of your own and enter the contest!

Our first Open Data Competition is now, well, open! The goal of the competition is to produce the coolest and most informative visualization* using two new Test Pilot datasets that we’ve just published: the results of the Week in the Life study v2, and the Firefox 4 Beta Interface study v2. The deadline for submissions is December 17. Find out more about the datasets and how to enter on the contest website.

* – Not limited to “visualization”, actually; we’ve already had one person ask us about turning the data into sound, which we think is totally cool. Not sure there’s a word in English that captures “visualization” as well as analysis based on other senses.
