GraphLink: Correlation or Causation?

Posted on January 17, 2012 by Corey

We ran across a good article on BusinessWeek a few weeks ago that shows us how graphs can easily be misused to demonstrate trends which may not exactly be connected.

This highlights the problem when people assume causation when it comes to trends in our societal data.

GraphGraph.com Month In Review – 2011-11

Posted on December 8, 2011 by Corey

Every month we’re going to attempt to do a meta-review of the site, using graphs of course.

Visitors

We had a “soft launch” towards the end of October with a few hits, but we really took off in November, starting with a post about my Halloween Candy experiences this year, which was shared out by Geekadelphia.

Red bars represent days with new posts, and Blue bars are days without new posts.

We thought an interesting stat to look at would be the number of pageviews per visitor. On days where the diamond is above 1, it represents where on average people clicked on something else within the site beyond just their initial entry page. The highest day for that was 11/10/2011, when Drew had his post on Scrabble.

All in all, we’re very happy that in our first month we had 737 visits and 1,049 pageviews. Thank you!

Four Degrees of Separation on Facebook

Posted on December 6, 2011 by Corey

Facebook has a great post up from their Data team about relationships between people, and more specifically concluding that the majority of Facebook users are only four degrees of separation away from anyone else on the social networking site.

From the article:

We found that six degrees actually overstates the number of links between typical pairs of users: While 99.6% of all pairs of users are connected by paths with 5 degrees (6 hops), 92% are connected by only four degrees (5 hops). And as Facebook has grown over the years, representing an ever larger fraction of the global population, it has become steadily more connected. The average distance in 2008 was 5.28 hops, while now it is 4.74.

Very fascinating findings! Read the full article for more information and some additional charts that tie everything together. And while you’re there, how about you go ahead and “Like” us on Facebook? Awesome! Thanks.
