The Super Big Bowl Game


The Super Bowl, excuse me, I should have said The Big Game, (since the NFL restricts their copyrighted name from all but their officially endorsed advertising), is tomorrow. The Pittsburgh Steelers play the Arizona Cardinals in Tampa. The Steelers home is Heinz Field shown in this view from Google Earth in 2006. Look at the two prominent areas of wear along each sideline of the field. These sidelines are where the players, coaches, and trainers watch, wait, and often pace as the game progresses. These areas of wear show us the frequency distribution of this sideline action. Coaches and players move up and down along the sideline following the action on the field. As they do so their steps wear away the turf underneath leaving a record as frequency distributions; more wear indicating a greater frequency of use.

If you look closely you can also see a wear pattern of the team's use of the field during play.

Microbes illustrate Simpson's Paradox


An article in Science by Chauang, Rivoire, and Leibler illustrates Simpson's paradox with a microbial system. They describe the principles with the illustration above from their paper. On the right three subpopulations undergo decreases in their percentage of green, but because of unequal weighting of the subpopulations the global population undergoes an increase.

Correlations of Google Search Rankings with State Statistics


This StateStats site is fun. The states are shown in relative rankings of an entered search term. Here I searched for the word "beatles". Spearman rank correlations are then calculated for these search rankings and state ranking of statistics such as population density, income, or percent voting for Obama. States with the most searches for the word "beatles" are negatively correlated with those states that voted for Bush in 2004 and positively correlated with those states that voted for Obama in 2008. Examples on the site reveal interesting correlation patterns for searches for terms like, prius or nascar. The site warns that correlation is not causation.
