The Consumer Price Index $\text{(CPI)}$ measures changes in retail prices, and hence, it is also known as retail price index numbers. It measures the average changes in retail prices to show the accurate impact of price rise on the cost of living of the people.
In the Weighted Method of calculating index numbers, different goods are accorded weights according to the quantity brought. Laspeyre’s method uses base year’s quantities as weights, Paasche’s method uses current year’s quantities as weights and Fisher's method uses both base year as well as current year’s quantities as base.
Whether the change in price will be reflected in a price index number or not depends on the weight associated with the item. Lower or negligible weight reflects lower or negligible change in the index number and higher weight reflects higher change in the index number.
