10 Difficulties faced in the Construction of Index Numbers | Economics
- Difficulties in the Selection of the Base Period:
- Difficulties in the Selection of Commodities:
- Difficulties in the Collection of Prices:
- Arbitrary Assigning of Weights:
- Difficulty of Selecting the Method of Averaging:
What are the factors to consider when constructing index numbers?
In constructing an index number, the following steps should be noted:
- Purpose of the Index Number: ADVERTISEMENTS:
- Selection of Commodities:
- Selection of Prices:
- Selection of an Average:
- Selection of Weights:
- Selection of the Base Period:
- Selection of Formula:
Which is the best method for construction of index numbers?
In general, construction of index number is further available for the division in two parts: Simple and Weighted. Furthermore, the simple method is classified into simple aggregative and simple relative. Similarly, the weighted method is classified into weighted aggregative and weighted average or relative.
What is an index number point out its utility and limitations?
An index is a number which shows how average of commodity prices (wholesale or retail prices), wages, etc., change over time. This will enable us to compare the price movements over different time periods. ADVERTISEMENTS: Time series data are expressed in terms of index numbers.
What is implied by the assignment of weights in the construction of the index numbers?
Assigning proper weights: Weight refers to the relative importance of the different items in the construction of an index number. Weights are of two types i.e. quantity weights (q) and value weights (p x q). Since all items are not of equal importance, by assigning specific weights, better results can be achieved.
What are the steps involved in the construction of index number explain any two?
Choice of a suitable average: Construction of index numbers requires the choice of a suitable average. Assigning proper weights: Weight refers to the relative importance of the different items in the construction of an index number. Weights are of two types i.e. quantity weights (q) and value weights (p x q).
What is the main purpose for construction of index numbers explain with examples?
The purpose of these index numbers is to measure time to time changes in money wages. These index numbers, when compared with the working class cost-of-living index numbers, provide information regarding the changes in the real wages of the workers.
What are index number limitations?
Limitations of Index Number
- There are chances for errors given that index numbers come as a result of samples.
- It is always calculated based on items.
- Multiple methods can be used to formulate index numbers.
- The index numbers show the approximate indications of the relative changes that occur.
What do you mean by index numbers describe briefly the problems involved in the construction of index numbers of prices?
Selection of items : Collection of data is the main problem in constructing index number, as there is a large variety of goods and prices. If the number of the commodities is too large, a choice of some representative items has to be made. Price quotations : The prices of commodities vary from place to place.
Why is index number important?
Index numbers are most important in economic status. An Index number defines the level of a variable relative to its level in a given period. Index numbers are also used to study the change in effects of factors which cannot be measured/ calculated directly.
