Balancing the numbers

Bruce Barry at the Nashville Scene has being doing some number crunching. He's wondering why they don't add up.

The problem is that the cluster data do not match the overall data. The results released Friday by MNPS show the balanced calendar prevailing in nine of eleven clusters, in all but one case by a margin of at least five percentage points. This might give most board members the impression that their constituents favor the change by a non-trivial margin. But: How can there be such cluster-by-cluster support for the balanced calendar when the overall household poll showed an evenly divided survey result?

Here's the link to his Pith in the Wind post hosted by the Nashville Scene. You'll want to read the rest.
