Crossword Puzzle: A Touch of Math

Here is an original 15×15 crossword puzzle I constructed, called “A Touch of Math“.

A Touch of Math 2011 – Patrick Honner

I would rate this puzzle as easy, suitable for those without much puzzling experience.

As the title suggests, you don’t need any special mathematical knowledge to complete this puzzle.  All of the long clues, and a few short ones, are math-related, but by no means is it entirely mathematical (constructing such a puzzle would be extremely difficult!).

Try it yourself, and feel free to use it with your students.

Rating the Ballparks

baseball-stadium-rankingsIn an attempt to rate the various Major League Baseball stadiums around the country, Nate Silver looked at the user ratings from online review site Yelp.  Noting that every ballpark has at least several hundred user reviews, Silver compiled the data from Yelp’s 1 to 5 rating system to create an ordering of the stadiums.  Once complete, the list creates a natural starting point to investigate questions like “Is ballpark satisfaction correlated with team performance?” and “How valuable is a retractable-roof stadium?”

Silver also provides the standard deviation for the ratings for each ballpark and explains the significance.  Standard deviation is a measure of the dispersion of data, so a higher deviation means more extreme ratings.

A great, fun little project!  What else can we rate using available user ratings?
