Google Public Data Explorer

Google’s Public Data Explorer is a great, free resource for students and teachers interested in data science and statistics.

http://www.google.com/publicdata/home

The site allows you to create custom graphs of available data sets, making it easy to experiment with different representations and explore the meaning of data.

There are several data sets available to play around with.   The OECD Factbook alone provides a wealth of raw data on education, energy, employment, population and migration, and many other categories.  There are also data sets available from the U.S. Census and the U.S. Bureau of Economic Analysis.  There appears to be support for using your own data sets, as well.

The data can be represented in a variety of ways:  histograms, line graphs, and even dynamic time series are all available.  It’s a great way to play around with data, and to build skill and intuition in data analysis, interpretation, and representation.

Bike Data Visualization

This is a cool visualization of bicycle usage in London:

On October 4th, 2010, there was a public transit strike in London, which maximized bike usage in the city.

The creators claim that the flashes of light that represent the bikes move in accordance with the actual speed and path of the bikes they represent.

An innovative representation that puts me in mind of graph theory and networking!

Applications of Government Data

This is a nice resource from The Guardian that highlights some of the ways developers are making government data accessible to citizens.

The projects include housing price analysis, roadway usage, government spending, and aggregation of community information.

The site wheredoesmymoneygo.org is especially interesting:  slide the bar to your yearly income, and see just how much of your salary is spent on education, health services, defense, and other categories.

Lots of applications to play around with, and plenty of food for thought!

2010 Census Map

This is another beautiful infographic from the New York Times that allows the user to interact with data from the 2010 U.S. Census.

Rotten Tomato Analysis

This is a cool collection of data analysis from Slate.com that uses scores from the movie review site RottenTomatoes.com to chart the careers of actors and directors.

http://www.slate.com/id/2296070/

In addition to comparing the average career trajectories of actors and directors (a curious result!) and provoking interesting questions like “Why does the average rating seem to be falling over time?”, Slate provides a great little toy to play with:  the Hollywood Career-o-Matic.

Type the name of any actor or director into the Career-o-Matic and see a quantitative overview of that person’s film history graphed out in front of you!  You can even type multiple names and compare graphs!  Scrolls over the highs (and lows) to get film details.

A nice little data tool, and it’s easy to see some fun, informal data projects coming from this.  And it looks like it all started with this brilliant critique of M. Night Shyamalan.
