• ### Unweighted Index Numbers

There are two methods of constructing unweighted index numbers. (1) Simple Aggregative Method (2) Simple Average of Relative Method Simple Aggregative Method: In this method, the total of the prices of commodities in a given (current) years is divided by the total of the prices of commodities in a base year and expressed as percentage. […]

• ### Chain Base Method

In this method, there is no fixed base period. The year immediately preceding the one for which price index have to be calculated is assumed as the base year. Thus, for the year1994 the base year would be 1993, for 1993 it would be 1992 for 1992 it would be 1991 and so on. In […]
