## Explain the concept and uses of index numbers

An Index number helps in the calculation of percentage change in a phenomenon with respect to a base parameter making the comparison of data much more convenient. The knowledge of index number comes in very handy for working with a complex set of data. Index numbers are used to measure changes in the value of money. A study of the rise or fall in the value of money is essential for determining the direction of production and employment to facilitate future payments and to know changes in the real income of different groups of people at different places and times. Index numbers may be classified in terms of the variables that they are intended to measure. In business, different groups of variables in the measurement of which index number techniques are commonly used are (i) price, (ii) quantity, (iii) value and (iv) business activity. This index number is a useful number that helps us quantify changes in our field. It is easier to see one value than a thousand different values for each item in our field. Take the stock market, for example. It is comprised of thousands of different public companies. The primary purposes of an index number are to provide a value useful for comparing magnitudes of aggregates of related variables to each other, and to measure the changes in these magnitudes over time. Consequently, many different index numbers have been developed for special use. There are a number of particularly well-known ones, some of which are announced on public media every day. Meaning of Index Number of Prices: An index is a number which shows how average of commodity prices (wholesale or retail prices), wages, etc., change over time. Index numbers are expressed in absolute form. An index number of prices is an index of the prices of goods and services bought by the household. An index number is a statistical device used to express price changes as a percentage of prices in a base year (or at a base date). (This base date is indicated by a phrase such as ‘1980= 100’.) In this case, movement in prices are expressed as percentage changes over the average level prevailing in 1980.
