Question 1.
What are the limitations of index numbers?
Answer:
The limitations of index numbers are mentioned below.

• Index numbers are not fully true.
• They do not help in international comparison.
• They are prepared with certain specific objectives.
• It is difficult to collect retail prices. So, index numbers based on wholesale prices may be misleading.

Question 2.
“Index number is used in economics for policymaking” substantiate.
Answer:
Wholesale price index number (WPI), consumer price index number (CPI) and industrial production index (IIP) are widely used in policymaking.

1. Consumer index number (CPI) or cost of living index numbers are helpful in wage negotiation, formulation of income policy, price policy, rent control, taxation and general economic policy formulation.

2. The wholesale price index (WPI) is used to eliminate the effect of changes in prices on aggregates such as national income, capital formation, etc.

3. WPI is widely used to measure the rate of inflation. Inflation is a general and continuing increase in prices. If inflation becomes sufficiently large, money may lose its traditional function as a medium of exchange and as a unit of account. Its primary impact lies in lowering the value of money.

4. CPI are used in calculating the purchasing power of money and real wage.

5. Index of industrial production gives us a quantitative figure about the change in production in the industrial sector.

6. Agricultural production index provides us a ready reckoner of the performance of agricultural sector.

7. Sensex is a useful guide for investors in the stock market. If the sensex is rising, investors are optimistic of the future performance of the economy. It is an appropriate time for investment.

Plus One Economics Index Numbers Five Mark Questions and Answers

Question 1.
Certain important issues should be kept in mind while constructing an index number”. Do agree? Substantiate your answer.
Answer:
Yes, certain important issues should be kept in mind, while constructing an index number. Those issues are mentioned below

1. You need to be clear about the purpose of the index. The calculation of a volume index will be inappropriate when one needs a value index.

2. Besides this, the items are not equally important for different groups of consumers when a consumer price index is constructed. The rise in petrol price may not directly impact the living condition of the poor agricultural labourers.

Thus the items to be included in any index have to be selected carefully to be as representative as possible. Only
then you will get a meaningful picture of the change.

3. Every index should have a base. This base should be as normal as possible. Extreme values should not be selected as base period. The period should also not belong to too far in the past. The comparison of between 1993 and 2005 is much more meaningful than a comparison between 1960 and 2005.

Many items in a 1960 typical consumption basket have disappeared at present. Therefore, the base year for any index number is routinely updated.

4. Another issue is the choice of the formula, which depends on the nature of question to be studied. The only difference between the Laspeyres index and Paasche’s index is the weights used in these formulae.

5. Besides, there are many sources of data with different degrees of reliability. Data of poor reliability will give misleading results. Hence, due care should betaken in the collection of data. If primary data are not being used, then the most reliable source of secondary data should be chosen.

Question 2.
Explain various types of index numbers.
Answer:
Some Important Index Numbers
1. Consumer price index:
Consumer price index (CPI), also known as the cost of living index, measures the average change in retail prices. The CPI for industrial workers is increasingly considered the appropriate indicator of general inflation, which shows the most accurate impact of price rise on the cost of living of common people.

2. Wholesale price index:
The wholesale price index number indicates the change in the general price level. Unlike the CPI, it does not have any reference consumer category. It does not include items pertaining to services like barber charges, repairing, etc.

3. Industrial production index:
The index number of industrial production measures changes in the level of industrial production comprising many industries. It includes the production of the public and the private sector. It is a weighted average of quantity relatives. In India, it is currently calculated every month with 1993 – 94 as the base.

4. Index number of agricultural production:
The index number of agricultural production is a weighted average of quantity relatives. Its base period is the triennium ending 1981 – 82. In 2003 – 04 the index number of agricultural production was 179.5.

It means that agricultural production has increased by 79.5 percent over the average of the three years 1979 – 80, 1980 – 81 and1981 – 82. Foodgrains have a weight of 62.92 percent in this index.

5. Producer Price Index:
The producer price index number measures price changes from the producers’ perspective. It uses only basic prices including taxes, trade margins, and transport costs.

Answer:

Question 9.
Calculate coefficient of correlation using the following data.

Answer:

Plus One Economics Correlation Five Mark Questions and Answers

Question 1.
What do you mean by Spearman’s rank correlation coefficient? Point out the situations where it is used. Also, bring about its usefulness.
Answer:
Spearman’s rank correlation was developed by the British psychologist C.E. Spearman. It is used when the variables cannot be measured meaningfully as in the case of price, income, weight, etc. The ranking may be more meaningful when the measurements of the variables are suspect.

There are also situations when you are required to quantify qualities such as fairness, honesty, etc. Ranking may be a better alternative to the quantification of qualities. Moreover, sometimes the correlation coefficient between two variables with extreme values may be quite different from the coefficient without the extreme values. Under these circumstances, rank correlation provides a better alternative to simple correlation.

Rank correlation coefficient and simple correlation coefficient have the same interpretation. Its formula has been derived from simple correlation coefficient where individual values have been replaced by ranks. These ranks are used for the calculation of correlation. This coefficient provides a measure of linear association between ranks assigned to these units, not their values. It is the Product Moment Correlation between the ranks.

Question 2.
“Correlation Coefficient has certain essential properties”-substantiate.
Answer:
Correlation Coefficient has certain essential properties as discussed below.
1. r has no unit. It is a pure number. It means units of measurement are not part of r. r between height in feet and weight in kilograms, for instance, is 0.7.

2. A negative value of /-indicates an inverse relation. A change in one variable is associated with change in the other variable in the opposite direction. When price of a commodity rises, its demand falls. When the rate of interest rises the demand for funds also falls. It is because now funds have become costlier.

3. If r is positive the two variables move in the same direction. If/”= 0 the two variables are uncorrelated. There is no linear relation between them. However other types of relationships may be there.

4. If r = 1 or r = -1 the correlation is perfect. The relation between them is exact.

5. A high value of r indicates strong linear relationship. Its value is said to be high when it is close to+1 or-1.

6. A low value of r indicates a weak linear relation. Its value is said to be low when it is dose to zero.

7. The value of the correlation coefficient lies between minus one and plus one, -1 < r < +1. If, in any exercise, the value of r \s outside this range indicates error in calculation.

8. The value of r is unaffected by the change of origin and change of scale. Given two variables X and Y let us define two new variables.

i. Positive correlation
ii. Perfect positive correlation
