Index Numbers (Class 12)

Index numbers are statistical tools used to measure changes in the level of a variable or a group of related variables over time, location, or situation. They are widely used in economics, business, and statistics to study trends, compare data, and analyze changes in prices, production, or quantities.

In Class 12, the topic covers the meaning, importance, and types of index numbers such as Price Index, Quantity Index, and Value Index. Students also learn methods of constructing index numbers, including the Simple Index Method and the Weighted Index Method (Laspeyres, Paasche, and Fisher’s Ideal Index).

The chapter emphasizes practical applications, like studying inflation, cost of living, industrial production, and trade. It also highlights the limitations of index numbers, such as sampling errors, changes in quality of goods, and difficulty in selecting a proper base year.

Overall, index numbers are essential for understanding economic fluctuations and guiding decision-making in policy, business, and daily life.
