Fun with numbers (3)

According to the Halifax House Price Index, the average house price in April 2007 was £196,252, and in April 2008 it was £189,027 (see page 4 of 4). They reckon that's a fall of 0.9% year-on-year.

Er ... £189,027 divided by £196,252 is 96.3%. Isn't that a fall of 3.7%?

Or put it this way; the average price in August 2007 was £199,600, so prices have fallen 5.3% in 7 months, that's about 9% annualised. So there.
