My US GDP/”Population” Map

Yes, the quality on this is not super high, but the point is to experiment with an idea.

There has been a lot of controversy floating around about a map.

… to name a few.

The map being this: http://www.reddit.com/r/MapPorn/comments/1y371s/

I have a thing for trying out abstract ideas in spacial analysis. Like:

As a western Canadian, I’m very aware of the east-west dynamics in the US and Canada, so I thought I would follow a hunch and make this map. I think it demonstrates nicely how lop-sided the US is.

Average shot locations in the paint and at midrange

Yet another post on visualising and analysing NBA shot location data using location averaging methods.

Previously I have shown averages by team for all shots taken. What about shots taken by zone? Consider the following two charts:

avg_inthepaint_teams

avg_midrange_teams

Now we can see a level of detail that we couldn’t in the average of all shots.

Previously:

Observations:

  • Previously we saw that the GSW were the longest shooters in the league and indeed they were also long shooters in the paint and at midrange. It is not simply that the GSW take a lot of 3s.
  • Other teams like the NYK take shots from close up in both the paint and at midrange. They were generally longer shooters in the previous analysis, suggesting that they balance those close 2-pts with many 3-pt attempts
  • Previously we saw DEN as the closest shooters overall, and indeed they appear to be close shooters in the paint and moderately close shooters at midrange.

NBA players shoot from further as the game progresses

On average, players in the NBA take shots 6.5% further from the basket in the 4th period than in the 1st. This is a subtle, but consistent trend across all periods. 1.2% further in the 2nd than the 1st, 2.4% further in the 3rd than the 2nd, and 2.7% further in the 4th than the 3rd.

Most teams show the same trend, consider the graphic Average Distance of Shots by Period below:

avg_distance_period_allteams

 

Nearly all teams show an increasing distance by period, but there are some notable exceptions. A few teams like NYK, UTA, ATL, and ORL show an opposite trend.

It’s not clear at this point what is leading this. Greater defense in later periods forces further shots? A greater need for 3-pts pushes shots away from the basket? A greater need for points in less time forces less ideal shots from further out? What about the exceptional teams where they get closer? What are these teams doing in the 4th quarter? Leaning more heavily on particular strengths or players?  Tired players not driving to the net?

What is true at the global level and largely true at the team level is again reflected in the players. Here are the average distance for the top 100 scorers:

More noise, but the trend is still visible!
