Competitive balance and home court advantage in the NBA

Two years ago, the entire NBA season went into lockout because of mostly financial reasons. However, one central point was also about keeping a competitive balance within the NBA, so that large and small-market teams alike would have a chance to compete for a championship. THis brings us to the obvious question “Is there competitive

In order to achieve their goal of still playing this time next year, teams often look to improve their roster through trades, player development, and most importantly, the

Using sentiment analysis to predict ratings of popular tv series

Unless you’ve been living under a rock for the last few years, you have probably heard of TV shows such as Breaking Bad, Mad Men, How I Met Your Mother or Game of Thrones. While I generally don’t spend a whole lot of time watching TV, I have also undergone some pretty intense binge-watching sessions

On the carbon footprint of the NBA

It’s no secret that I enjoy basketball, but I’ve often wondered about the carbon footprint that can be caused by 30 teams each playing an 82-game season. Ultimately, that’s 2460 air flights across the whole of the USA, each carrying 30+ individuals. For these reasons, I decided to investigate the average distance travelled by each NBA

On the trade history and dynamics of NBA teams

While good draft picks and deft management can help you win championships, there is no doubt that NBA teams can massively gain, or lose, by trading players with one another. Here, I played around with some publicly available data given at basketball-reference.com, and had a look at the numbers behind all trades undertaken in the NBA from 1948 to

And the most loyal fans in the NBA are…

NBA basketball is the one the sports I enjoy watching the most. As I was ordering my (undisclosed amount)th beer while watching a game during after-work hours, it occurred to me how often I had seen sparsely populated arenas during games, with large areas of seats going unoccupied. This got me to thinking about the

On the rise of Big Data and Data Science

This post is going to differ slightly from the data-orientated material that I usually publish. I was recently playing around with the Google trends API and came across some very interesting…well….trends. There has definitely been a huge amount of publicity surrounding “Big Data”, maybe even too much. For those of us who have been working

President Approval Ratings from Roosevelt to Obama

I have been watching the awesome Netflix show “House of Cards” and been fascinated by the devious schemes that Underwood is constantly plotting. The show often mentions approval ratings and it got me to wondering what Obama’s ratings currently were, and all other past US president  for that matter. However, I didn’t have much chance

Which states are the most concerned by gun crime?

I recently discovered the Capitol Words API and have had some fun playing around with it. One of the categories in the API allows you to search for the words spoken by the senators of each state in the USA, and I was interested in finding out the number of times the words “gun” were recorded on a
