What is the formula of chain base index number?
This index type is called a chain index because individual indices with previous period = 100 can be chained together by multiplying (and dividing by 100) all consecutive indices, thus converting them into a series of indices with the first reference period = 100.
What is chain base method?
⇒ In chain base method, the base period is : Notfixed. ⇒ In this method, there is no fixed base period; the year immediately preceding the one for which the price index has to be calculated is assumed as the base year.
How do you calculate relative chain?
Link relatives are calculated by dividing the figure of each season* by the figure of immediately preceding season and multiplying it by 100. These percentages are called link relatives since they link each month (or quarter or other time period) to the preceding one.
How do you calculate fixed base index?
The fixed base method is used by the government in the calculation of national index numbers….Fixed Base Method.
| Year | Price | Index nos 1980 as base Pon=PnPo×100 |
|---|---|---|
| 1985 | 100 | 10040×100=250 |
| 1986 | 90 | 9040×100=225 |
| 1987 | 110 | 11040×100=275 |
What are the uses of chain base index number?
Advantages of Chain Index Numbers Method
- This method allows the addition or introduction of the new items in the series and also the deletion of obsolete items.
- In an organization, management usually compares the current period with the period immediately preceding it rather than any other period in the past.
What is link relative in index number?
In index number theory, the value of a magnitude in a given period divided by the value in the previous period.
What is fixed base and chain based method?
In fixed base method, the year selected for construction of index numbers remains constant for all times and the base shall remain fixed. While in chain base method the base year is changed every year, generally preceding year and not fixed year.
How many types are used for the calculation of index number?
There are basically two types of index numbers: price index number and quantity index number.
What is chained GDP?
GDP at chained volume measure is a series of GDP statistics adjusted for the effect of inflation to give a measure of ‘real GDP’.

How an index is calculated?
The index is calculated by tracking prices of selected stocks (e.g., the top 30, as measured by prices of the largest companies, or top 50 oil-sector stocks) and based on pre-defined weighted average criteria (e.g., price-weighted, market-cap weighted, etc.)
How do you find the relative of a chain?
How to find the chain index of a given year?
(1) The figures are to be expressed as the percentage of the preceding year to get link relatives. (2) Chain index is obtained by the formula : Example 8: From the following data find the index numbers by taking (1) 2005 as base (ii) by chain base method.
Can we change the base period in chain index numbers?
Thus, in such a situation changing the base period is more appropriate. Chain Index Numbers method is one such method and we shall discuss it now in detail. Under this method, firstly we express the figures for each year as a percentage of the preceding year. These are known as Link Relatives.
What are the advantages of the chain base method of indexing?
Another advantage of the chain base method is that it is possible to include new items in an index number or to delete old times which are no longer important.
What is the base year in chainchain method?
Chain Base Method In this method, there is no fixed base period; the year immediately preceding the one for which the price index has to be calculated is assumed as the base year. Thus, for the year 1994 the base year would be 1993, for 1993 it would be 1992, for 1992 it would be 1991, and so on.
