Explanation:
The value index is a measure used to compare the value of a variable in a given year with the value of the same variable in a base year. It is used to track changes in the value of a variable over time.
The correct answer is option B, which states that the value index is equal to the total sum of the values of a given year divided by the sum of the values of the base year. This is the correct formula for calculating the value index.
Calculation:
To calculate the value index, you need to follow these steps:
1. Determine the total sum of the values of the variable in the given year.
2. Determine the total sum of the values of the variable in the base year.
3. Divide the total sum of the values of the given year by the total sum of the values of the base year.
The result of this calculation will give you the value index, which represents the relative change in the value of the variable between the given year and the base year.
Example:
Let's consider an example to illustrate the calculation of the value index:
Suppose we want to calculate the value index for the variable "Gross Domestic Product (GDP)" for the year 2020 compared to the base year 2015.
1. Determine the total sum of the GDP values for the year 2020.
Let's say the total sum of the GDP values for 2020 is $10 trillion.
2. Determine the total sum of the GDP values for the base year 2015.
Let's say the total sum of the GDP values for 2015 is $8 trillion.
3. Divide the total sum of the GDP values for 2020 by the total sum of the GDP values for 2015.
In this case, the value index would be 10/8 = 1.25.
Therefore, the value index for GDP in 2020 compared to the base year 2015 is 1.25. This indicates that the GDP in 2020 is 25% higher than the GDP in 2015.
Conclusion:
In conclusion, the value index is a measure used to compare the value of a variable in a given year with the value of the same variable in a base year. The correct formula for calculating the value index is the total sum of the values of the given year divided by the total sum of the values of the base year.
