Why do they report the median year over year? There’s no good reason for it. Why not report gas prices year over year too?

Unlike the past decades, the new home median has been very volatile the last 3 years; example: $500K June 03, $435K Feb 05, $540K Dec 05,$435K Jan 06. In August it was $395K, so September’s $413K was an increase over August. So with that much volatitility, I wouldn’t make a big deal about any one month changes (year over year included).
