How can these elements in one's statistical education be secured? The difficulties in the way of the best statistical work are not slight. Dr. Dewey, in a recent address upon average prices, before the American Statistical Association, gave an exceedingly valuable, and a very clear explanation of the difficulties which underlie all efforts to secure average prices ranging over a period of years ; he pointed out the different methods of securing such averages, and I can do no better than to use ...Dr. Dewey's own words, as taken from the address referred to. He says : 1 ' There is first the ordinary * index method ' introduced by Mr. Newmarch, and continued by the Economist and Mr. Jevons. In this there is no attempt to take account of the varying importance of the commodities where prices are averaged together, but equal con- sideration is given to all. "A second method is to give each commodity, where price enters into the averages, a weight proportionate to the quantity of it sold during a fixed period of time.
