Appeared in: DSSSB 6 September 2024

Explanation

• The correct term is Consumer Price Indices (CPI), which is the standard economic measure for this purpose.
• A price index is a normalized average of price relatives for a given class of goods or services in a given region, during a given interval of time.
• It tracks the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care.
• It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.

Why Other Options Were Wrong

• Option A: The 'I' in the acronym CPI stands for 'Index' or 'Indices', not 'Indicators'. While the CPI is an economic indicator, that is not its formal name.
• Option B: Inflation is the economic phenomenon that the CPI measures. The index itself is not called 'Consumer Price Inflation'.
• Option D: CPD is not a standard economic acronym. Deflation is a decrease in the general price level, which would be indicated by a negative change in the CPI, but it is not the name of the index.

• Focus on the meaning of 'I' in CPI. Recall or deduce that 'Index' is a standard term for a statistical measure that tracks changes.
• Differentiate between the name of the measure (the Index) and the phenomena it measures (Inflation and Deflation). This helps eliminate 'Consumer Price Inflation'.
• Eliminate 'Consumer Price Indicators' as 'Index' is the precise term.
• Eliminate 'Consumer Price Deflation (CPD)' as it's not a standard term and confuses the measure with the outcome.
