Yes.
A base period for an index number serves as the reference point for comparison with other periods. It is typically assigned a value of 100 for simplicity in calculations. The base period allows for tracking changes in the index over time relative to a fixed point.

The value of the variable in the base period forms the basis of comparison of the variable in other periods.
Index is generally the homepage of a website. It is the main or the first page which appears.
To get index number trend analysis, you need a set of data points representing the index numbers over a specific time period. Plotting the data on a graph will allow you to visually analyze the trend. Additionally, you can calculate the average change in index numbers over time using a formula such as the percent change formula or the moving average method to identify the direction and rate of the trend.
what is index number
In the simplest case, you select one period to represent the base period. Suppose the value of the variable for this period is V. The index is calculated by multiplying the value for each period by 100/V. This results in the base period having an index of 100 and all the other periods are represented by their percentage relative to the base period. Things get more complicated when you consider (mainly) economic index numbers such as price indices. A simplistic description of a price index is as follows: identify a "basket" of goods and services that the price index is required to cover. Calculate a price index for each item using the same base year. Then calculate the weighted average of these indices, where the weights reflect the importance of the goods in the total spend - either in the base period or the current period.
uses of index
They are called index fossils.
Final price index = 140 Initial price index = 125 Therefore, difference in price index between period 3 and 4 is : 140 - 125 = 15 Lastly, 15/125 * 100 = 12%
The time reversal test is a criterion for assessing the consistency of index numbers, particularly in the context of economic measures like price indices. It states that if an index number measures the change in a variable from time period A to B, then reversing the time period (from B back to A) should yield the reciprocal of the original index. If an index satisfies this condition, it demonstrates consistency, indicating that the measure is stable and reliable across time periods. However, not all index numbers satisfy this test, which can lead to discrepancies in interpretation.
