单词 | index_number |
释义 | Index number A way to standardize the price changes of goods that have much different prices. For example, a consumer price index might be represented by a shopping cart of goods. Suppose those goods cost $324. The index would begin by dividing by 3.24 and the initial value would be 100. One usually watches the percentage increases or decreases in the index.
