An index number measures the magnitude of a variable relative to a specified The choice of formula was made according to what was considered to be “fair. Thus, it is natural to construct a weighted arithmetic, harmonic, or geometric The S&P 500 is a stock market index that tracks 500 large-cap companies.

An index number is not an absolute measure, it measures the percentage change in a variable over time. It does so by comparing the value of a variable at present to its value at a base year. Index number gives a quantitative foundation to qualitative statements like prices are falling or rising. An index is a composite measure of variables, or a way of measuring a construct--like religiosity or racism--using more than one data item. An index is an accumulation of scores from a variety of individual items. To create one, you must select possible items, examine their empirical relationships, score the index, and validate it. So if the current index number is 180, it means that prices have increased 80% since then, according to the Bureau of Labor Statistics. If we look at this index for September 2014, we see that the index is at 243.623. This means that since 1982, prices of goods have increased by 143.623%. Basic Index Number Theory. A. Introduction. The answer to the question what is the Mean of a given set of magnitudes cannot in general be found, unless there is given also the object for the sake of which a mean value is required. An index number is an economic data figure reflecting price or quantity compared with a standard or base value. [4] [5] The base usually equals 100 and the index number is usually expressed as 100 times the ratio to the base value. The construction of the price index numbers involves the following steps or problems: The first step or the problem in preparing the index numbers is the selection of the base year. The base year is defined as that year with reference to which the price changes in other years arc compared and expressed as percentages.
