The phenomenon or variable under consideration may be:  \n(1) The price of a particular commodity like steel, gold, leather, etc., or a group of commodities like consumer goods, cereals, milk and milk products, cosmetics, etc.  \n(2) Volume of trade, factory production, industrial or agricultural production, imports or exports, stocks and shares, sales and profits of a business house and so no.  \n(3) The national income of a country, wage structure of worker in various sectors, bank deposits, foreign exchange reserves, cost of living of persons of a particular community, class or profession and so on.  \nIn other words, an index number measures how much a variable changes over time. We calculate an index number by finding the ratio of the current value to a base value.  \n“Index numbers are statistical devices designed to measure the relative change in thelevel of a phenomenon (variable or a group of variables) with respect to time, geographical location or other characteristics such as income, profession, etc.”  \nFor example, suppose we are interested in studying the general change in the price level of consumer goods, i.e., goods or commodities consumed by the people belonging to a particular section of society, say, low income group or middle income group or labour class and soon. Obviously these changes are not directly measurable as the price quotations ofthe various commodities are available in different units, e.g., cereals (wheat, rice, pulses, etc.) are quoted in Rs. per quintal or kg.; water in Rs. per gallon; milk, petrol, kerosene, etc., in Rs. Per litre; cloth in Rs. per metre and so on.  \nFurther, the prices of some of the commodities may to increasing while those of others may be decreasing during the two periods and the rates of increase or decrease maybe different for different commodities. Index number is a statistical device, which enables us to arrive at a single representative figure, which gives the general level of the price of the phenomenon (commodities) in an extensive group.  \nStock Market Indices  \nA stock market index is an index number that measures the movement in share prices of stocks under consideration.  \nTypes of Stock Market Indices  \nIndices can be categorized on the following basis:  \n1.Based on Size  \n2.Based on Nature  \n3.Based on Calculation Methodology  \nDifferent indices based on size  \n| SENSEX | Constituted of 30 scrips |\n| --- | --- |\n| BSE-100 | Constituted of 100 scrips |\n| BSE-500 | Constituted of 500 scrips |\n| Nifty | Constituted of 50 scrips |\n| Nikkie Index | Constituted of 225 scrips |\n| S & P 500 | Constituted of 500 scrips |\n| NASDAQ Composite | Constituted of around 4700 scrips |\n\nDifferent indices based on Nature  \nSENSEX Broad-based index representing all major industries from the  \nlisted universe  \n| BSE IT Sector Index | Index representing the IT sector stocks |\n| --- | --- |\n| BSE TECk Index | Index representing the TMT sector stocks |\n| BSE Healthcare Index | Index representing the Healthcare sector stocks |\n| FTSE-TMT Index | Index based on telecom, media and IT sector stocks |\n\nNasdaq-100 Index  \nTechnology Index  \nDifferent indices based on Calculation Methodology  \nNot all indexes are created in the same way.
