Chatroulette but sex
The central limit theorem tells us that a large set of random observations allows us to draw high-confidence conclusions about the underlying data set.We started our process at Chatroulette Map, an awesome new site that plots screenshots from random Chatroulette sessions on a map.
The good news, however, is that a roulette wheel is the statistician's best friend.Any images that were judged incorrectly could skew the results.It's also important to note that statistics about "the average chat session" (which we present here) are not the same as stats about "the average user." For example, imagine if female chats averaged 100 seconds each, but male chats averaged 10 seconds each.We coded up a quick webpage that displayed a random photo from the data set and asked some basic multiple-choice questions about that photo.These included questions on age, gender, and what the person in the photo was doing.If you haven't heard of Chatroulette, this Daily Show segment is a good primer.
We were itching to study Chatroulette in a RJMetrics Dashboard, but no one seemed to have any good data for us to explore.
Chatroulette Map is also nice enough to expose all of its data points to anyone who clicks "View Source." Right in the raw source code of their homepage is the image URL, latitude, longitude, city, state, and country of every chatter on their map.
As an added bonus, the file name of each image is a UNIX timestamp of when it was taken. (Note: we tried contacting the creators of Chatroulette Map to participate in this story but did not receive a response.)Once we had photos, times, and locations, we needed data on what was happening in each chat photo.
Even if there were equal numbers of male and female users, males would enter the pool more often and would therefore appear in front of you more often, making the "average session" more likely to contain a male chat partner.
Because of this, all of our statistics are about the average session and not the average user.
Most Chat Partners were Male Also interesting is the prevalence of groups on Chatroulette.
