Description
Indexes are used to measure the total impact of changes in the attributes of commodities which cannot be compared directly. In New Zealand the most common use of index numbers is to measure changes in prices, volumes , or money values over time. When calculating a price index the type, quantity , and quality of each commodity are all held constant so that the price movement can be measured.
