### A series of numerical figures which show the relative position is called

• A.

Index no.

• B.

Relative no.

• C.

Absolute no.

• D.

None

A. Index no.
Explanation
An index number is a series of numerical figures that represents the relative position of something. It is commonly used in economics and statistics to measure changes in variables such as prices, quantities, or economic indicators. Index numbers allow for comparisons and analysis of data over time or across different groups or regions. They provide a standardized way of expressing changes and trends, making it easier to interpret and understand data. Therefore, the correct answer is "Index no."

Rate this question:

### Index no. for the base peroid is always taken as

• A.

200

• B.

50

• C.

1

• D.

100

D. 100
Explanation
The index number for the base period is always taken as 100 because the base period is used as a reference point to compare the changes in the price level over time. By setting the index number for the base period as 100, it becomes easier to calculate the percentage changes in the price level for subsequent periods. This allows for a standardized and consistent measure of inflation or deflation.

### ____________ play a very important part in the construction of index nos.

• A.

Weights

• B.

Classes

• C.

Estimations

• D.

None

A. Weights
Explanation
Weights play a very important part in the construction of index numbers. Index numbers are used to measure changes in variables over time, such as inflation or stock market performance. In order to calculate an index number, different variables need to be given different weights based on their relative importance. These weights reflect the significance of each variable in the overall index. Therefore, weights are crucial in determining the accuracy and reliability of index numbers by ensuring that the index reflects the true changes in the variables being measured.

Rate this question:

### _______________ is particularly suitable for the construction of index nos.

• A.

H.M.

• B.

A.M.

• C.

G.M.

• D.

None

C. G.M.
Explanation
The Geometric Mean (G.M.) is particularly suitable for the construction of index numbers because it takes into account the relative changes in the values being compared. Index numbers are used to measure the average change in a set of values over time, and the G.M. is able to capture the multiplicative nature of these changes. This makes it a more accurate measure for calculating average changes in values such as prices or quantities.

Rate this question:

• 5.

### Index nos. show_________ changes rather than absolute amounts of change.

• A.

Relative

• B.

Percentage

• C.

Both

• D.

None

B. Percentage
Explanation
Index numbers show percentage changes rather than absolute amounts of change. This means that index numbers are used to compare the relative changes in a variable over time or between different groups, rather than measuring the actual amount of change. By using percentages, index numbers allow for easier comparison and analysis of trends, as they provide a standardized measure that is not affected by the scale or units of the variable being measured.

Rate this question:

• 6.

### The ___________ makes index nos. time-reversible.

• A.

A.M.

• B.

G.M.

• C.

H.M.

• D.

None

B. G.M.
Explanation
The geometric mean (G.M.) is the correct answer because it is the only measure out of the options provided that has the property of being time-reversible. The geometric mean is calculated by taking the nth root of the product of n numbers, and this calculation can be reversed by taking the nth power of the product of n numbers. Therefore, the geometric mean is the only measure that can be reversed in time.

### Index no.is equal to

• A.

Sum of price relatives

• B.

Average of the price relatives

• C.

Product of price relative

• D.

None

B. Average of the price relatives
Explanation
The index number is calculated by taking the average of the price relatives. This means that the sum of all the price relatives is divided by the total number of price relatives. This method is commonly used to measure changes in prices over time and is a way to represent the overall price level.

Rate this question:

• 9.

### The________ of group indices given the General Index

• A.

H.M.

• B.

G.M.

• C.

A.M.

• D.

None

C. A.M.
Explanation
The correct answer is A.M. (Arithmetic Mean). The arithmetic mean is the average value of a set of numbers. In this context, the "group indices" refer to a set of indices within a larger index, and the arithmetic mean of these indices is being compared to the "General Index". This suggests that the arithmetic mean is the appropriate measure to use in order to compare the average value of the group indices to the overall index.

### Weighted G.M. of relative formula satisfy ____________ test

• A.

Time Reversal Test

• B.

Circular test

• C.

Factor Reversal Test

• D.

None

A. Time Reversal Test
Explanation
The weighted geometric mean (G.M.) of relative formula satisfies the time reversal test. This means that if the values of the variables are reversed or switched, the result of the weighted G.M. of relative formula will also be reversed or switched. In other words, the order of the variables does not affect the outcome of the formula.

### Factor Reversal test is satisfied by

• A.

Fisher's Ideal Index

• B.

Laspeyres Index

• C.

Paasches Index

• D.

None

A. Fisher's Ideal Index
Explanation
The Factor Reversal test is satisfied by Fisher's Ideal Index. This index is designed to measure the overall price level and takes into account both current and base period quantities. It is considered ideal because it satisfies the factor reversal test, which means that if the roles of the base and current periods are reversed, the index still yields the same result. In other words, the index is not affected by the choice of base period, making it a reliable measure of price changes over time.

Rate this question:

• 14.

### Laspeyre's formula does not obey

• A.

Factor Reversal Test

• B.

Time Reversal Test

• C.

Circular Test

• D.

None

B. Time Reversal Test
Explanation
Laspeyre's formula is a method used to calculate a price index, which compares the price of a basket of goods and services in different time periods. The formula takes into account the quantities consumed in the base period and the prices in the current period. The factor reversal test is a property that a price index should satisfy, which states that reversing the base and current period quantities should result in the reciprocal of the original index. The circular test is another property that a price index should satisfy, which states that the index should not change if the base and current periods are swapped. However, Laspeyre's formula does not satisfy the time reversal test, which means that reversing the base and current periods does not result in the reciprocal of the original index.

### When the product of price index and the quantity index is equal to the corresponding value index then

• A.

Unit Test

• B.

Time Reversal Test

• C.

Factor Reversal Test

• D.

None holds

C. Factor Reversal Test
Explanation
When the product of price index and the quantity index is equal to the corresponding value index, it indicates that the change in price and quantity has resulted in a proportional change in the value of the product. This implies that the factor reversal test holds true, which states that if the price and quantity change in opposite directions but the value remains constant, then the factor reversal test is satisfied.

### The formula should be independent of the unit in which or for which price and quantities are quoted in

• A.

Unit Test

• B.

Time Reversal Test

• C.

Factor Reversal Test

• D.

None

A. Unit Test
Explanation
The correct answer is Unit Test. In order to ensure the accuracy and reliability of a formula, it should be independent of the unit in which price and quantities are quoted. This means that the formula should be able to produce the same result regardless of whether the price is given in dollars or euros, or whether the quantity is measured in kilograms or pounds. The unit test will help verify that the formula is indeed unit-independent and can handle different units of measurement correctly.

### Laspeyre's method and Paasche's method do not satisfy

• A.

Unit Test

• B.

Time Reversal Test

• C.

Factor Reversal Test

• D.

None

B. Time Reversal Test
Explanation
Laspeyre's method and Paasche's method are two commonly used methods for calculating price indices. Both methods have their limitations and do not satisfy the Time Reversal Test. The Time Reversal Test is a property that a price index should satisfy, which states that if all prices and quantities are reversed in time, the index should remain unchanged. In other words, if we reverse the order of the time periods, the index value should not change. This property is important to ensure the consistency and reliability of the price index. Therefore, since Laspeyre's method and Paasche's method do not satisfy this test, they may not be suitable for certain applications where the Time Reversal Test is crucial.

• D.

May not be

A. Yes
Explanation
The purpose of using an index in a database determines the type of index to use. Different types of indexes, such as B-tree, hash, or bitmap indexes, are designed to optimize specific types of queries or data access patterns. For example, if the purpose is to improve the performance of range queries, a B-tree index would be suitable. If the purpose is to quickly locate specific values, a hash index may be more appropriate. Therefore, the purpose of the index does determine the type of index to use.

• B.

False

• C.

Both

• D.

None

A. True
Explanation
The statement suggests that choosing a suitable base period is only a temporary solution. This implies that although selecting a base period may be helpful in the short term, it may not be a long-term or permanent solution. It implies that there may be other factors or variables that need to be considered in order to fully address the issue at hand. Therefore, the correct answer is True.

• B.

Factor Reversal Test

• C.

Both

• D.

None

C. Both
Explanation
Fisher's Ideal Formula for calculating index numbers satisfies both the Units Test and the Factor Reversal Test. The Units Test ensures that the index number is unaffected by changes in the unit of measurement, while the Factor Reversal Test ensures that multiplying all the quantities by a constant factor does not change the index number. Therefore, Fisher's Ideal Formula passes both of these tests, making the answer "Both" correct.

Rate this question:

• 28.

### Fisher's Ideal Formula dose not satisfy__________ test

• A.

Unit test

• B.

Circular Test

• C.

Time Reversal Test

• D.

None

B. Circular Test
Explanation
Fisher's Ideal Formula does not satisfy the Circular Test. The Circular Test is a statistical test used to determine if the residuals from a regression model are autocorrelated or not. Autocorrelation occurs when the residuals of a model are correlated with each other over time. Fisher's Ideal Formula is a statistical method used for combining p-values from multiple tests, and it does not take into account the autocorrelation structure of the data. Therefore, it is not suitable for use when autocorrelation is present, making it fail the Circular Test.

B. Do not satisfy
Explanation
Laspeyre's and Paasche's method do not satisfy the time reversal test. The time reversal test is a criterion used to determine the consistency of price index numbers. According to this test, if the index numbers are calculated in the reverse order using the same data, they should yield the reciprocal of each other. However, Laspeyre's and Paasche's methods do not meet this criterion and therefore do not satisfy the time reversal test.

### There is no such thing as unweighted index numbers

• A.

False

• B.

True

• C.

Both

• D.

None

A. False
Explanation
The given statement is false. Unweighted index numbers do exist. Index numbers are used to measure changes in a variable over time. Weighted index numbers give different weights to different components of the variable, while unweighted index numbers give equal weight to all components. Both weighted and unweighted index numbers are used in various fields such as economics, finance, and statistics. Therefore, the statement that there is no such thing as unweighted index numbers is incorrect.

Rate this question:

### Theoretically, G.M. is the best average in the construction of index nos. but in practice, mostly the A.M. is used

• A.

False

• B.

True

• C.

Both

• D.

None

B. True
Explanation
In theory, the geometric mean (G.M.) is considered the best average when constructing index numbers. This is because it takes into account the compounding effect of percentage changes over time. However, in practice, the arithmetic mean (A.M.) is often used instead. This is because the calculation of the G.M. can be more complex and time-consuming compared to the A.M. Additionally, the A.M. is easier to understand and interpret for most people. Therefore, even though the G.M. is theoretically superior, the A.M. is more commonly used in practice.
