The Weighted Aggregate Quantity Index In price index calculations, a change from “iPoqo to “ipnqo is due to changing prices because the quantity weights qo are held constant. Similarly, a change from “iPoqo to “iPoqn is due to changing quantities (qo to qn) because the price weights Po are held constant. In other words, the stocks with the higher prices will have more impact on the movement of the index than stocks with lower prices, since their price is "weighted" higher. For example, if a stock goes from $100 to $110, it will move the index more than a stock that goes from $20 to $30, even though Weighted Index Numbers Unlike simple index numbers, weighted index numbers, as the name suggests, weigh items according to their importance with respect to the concerned variable.
