Or, for that matter, "National Accounts Data"?RPI uses the arithmetic mean (add 'em all up, divide by the total).CPI uses the geometric mean (multiply 'em up, take the nth root).-oOo-Or at least, I think that's what the document said... :) Tue 17 Aug 2010 15:50:39 GMT+1 Phil I'm not, but the BBC obviously is.
