Statistics on real estate can be confusing

Standard and Poor's reported yesterday that Twin Cities housing prices suffered "the worst monthly decline of any metro area" in the history of its respected Case Shiller index. But the Minneapolis Area Association of Realtors measures the median sale price for homes in the metro, and they say prices actually increased during that same period.

MPR's Cathy Wurzer spoke with David Blitzer, a managing director in charge of indices at Standard & Poor's, about the difference between the two measurements.
