High School Swimming Success Using ArcGIS to predict the success of Fairfax County high school swim teams
Executive Summary Predict the success of a high school swim team based on the quantity of summer league swimmers that feed a particular school Determine how high schools are actually performing based on these predictions
Goals Use ArcGIS to plot the number of summer league swimmers that feed each high school Use ArcGIS to plot the success of each high school at the 2009 Regional Swim meet Determine if there is a correlation between the number of summer league swimmers and the success of the high school team at the 2009 Regional championships
Method Gather Fairfax County Public high schools boundary.shp file Gather Fairfax County Public high schools location.shp file Determine summer swim leagues in Fairfax County Collect pool addresses, and number of swimmers for each summer pool in Fairfax County Determine which high school boundary each pool is in Collect scores from the 2009 Regional Swim meet Geocode pool addresses to Fairfax County schools map Join geocoded pool addresses.shp file to high school boundary map Create a chroropleth map showing the results
Data Summer Swim Leagues Northern Virginia Swim League – 102 Pools, 15,000 Swimmers Colonial Swim League - 24 Pools, 2,500 Swimmers Herndon Swim League - 9 pools, 500 Swimmers Reston Swim League – 9 pools, 900 Swimmers
Analysis / Problems Pool Boundary does not fit high school Boundary (Several Examples) Geocoding could not find and address (Example) Thomas Jefferson High School
Analysis
Conclusions - Results
Pool exists, but is so new that it could not be geocoded because the roads maps are not new enough
Conclusions - Results Highest number of swimmers * McLean * Woodson * West Springfield Lowest number of swimmers * Edison * Hayfield * Mount Vernon
Conclusions - Results
Highest combined scores at Regionals * Robinson * Fairfax * Langley Lowest combined scores at Regionals * Hayfield * Mount Vernon * Stuart * Falls Church
Conclusion - Results Very difficult to predict which school will be the best (too many other factors) Very easy to predict which schools will not do well
Further Research Plot the number of year round swimmers that feed each high school Plot the individual addresses for each swimmer onto the high school boundary map Remove the dive scores from the regional meet scores
