A large number of commodities are offered for sale in every country of the world. If we study the behavior of the prices of the commodities in any market, we will soon arrive at a conclusion that they do not move in unison. There is every possibility that prices of some commodities may be going up and other falling. Even when the prices of all the commodities are changing in one direction, the rate of change may not be uniform. The prices of some commodities may be rising or falling faster than other. Index number is a device or an instrument which measure the average price movements of a number of selected commodities. In the words of Thomas" the index number is a device that permits the measuring of the average behavior of a number of individual prices.

Index numbers of different types work like a barometer showing fluctuations I the magnitude of a phenomena from time to time. One of these index numbers is the index number prices by means of which one can measure the changes in the value of money. If in a particular period there is 100 percent increase in the index number of prices it means100 percent decrease in the purchasing power of money or value of money.
