To provide website visitors with more choice about how their data is collected by Google Analytics, we have developed the Google Analytics Opt-out Browser Add-on. The add-on communicates with the Google Analytics JavaScript (ga.js) to indicate that information about the website visit should not be sent to Google Analytics.
If you want to opt out, download and install the add-on for your current web browser. The Google Analytics Opt-out Browser Add-on is available for Internet Explorer (versions 7 and 8), Google Chrome (4.x and higher), and Mozilla Firefox (3.5 and higher).

This is a self-initiated project based on the scenario – If the world were a village of 100 people. There are a few different versions of this text in circulation about the world’s statistics. I found the data very striking and neatly summarises the world that we live in. So I used information graphics to re-tell the story in another creative way. I designed a set of 20 posters, which contain most of the information. I used simple vector graphics that related to a statistic in order to present the information in the simplest and most accessible way.

The reason I am obsessed with self-tracking is because I think there is a way to track yourself in such a way that it leads to epiphanies about yourself, about the cause and effect of things, in such a way that these numbers would eventually be able to tell you things about yourself that you didn’t already know. This is the only reason to self-track, in my opinion.

As Gary mentioned in his earlier post, I track myself - 40 things about my body, mind, and activity - every day. The fact that I do this tracking seems to interest people. Whether they are driven by curiosity about the phenomenon of personal data collection, or by the desire for a yardstick by which to measure and compare themselves, the fascination exists. To address this interest, and by way of introducing myself as a hopefully regular guest blogger at The Quantified Self, I have put together a FAQ about my personal tracking. Read on and you'll probably know more about me than you ever wanted to know.

In statistics, a result is called statistically significant if it is unlikely to have occurred by chance. "A statistically significant difference" simply means there is statistical evidence that there is a difference; it does not mean the difference is necessarily large, important, or significant in the common meaning of the word.
