In a Marketwatch article titled, U.S. home prices decline 0.1% in December, Ruth Mantell explains that there was a 0,8% increase in home prices for the month. She apparently bases her headline on the fact that November prices rose 0.9%. Once again, we see another example of just how useless some statistics can be in the hands of the wrong people.
While the article does contain enough information for the average reader to understand that there is merely a slowdown in the increase in prices, not prices themselves, the headline suggests something else. Did the rate of increase in the increase decrease? Well, yes it did, but that's not what the headline says, is it? And how does the data affect potential home buyers? Probably not much.
