The formula for indexation can be simply derived by dividing the value of any subject good in any given year by the value of the same good in the base year, and then the result is multiplied by 100.

To index numerical data, values must be adjusted so they are equal to each other in a given starting time period. By convention, this value is usually 100. From there on, every value is normalized to the start value, maintaining the same percentage changes as in the nonindexed series.

Both indexing and sorting arrange rows in a specified order. However, indexing changes only the logical order and leaves the natural order intact, while sorting changes the natural order of the rows in the new table. Processing operations.

Indexing, broadly, refers to the use of some benchmark indicator or measure as a reference or yardstick. In finance and economics, indexing is used as a statistical measure for tracking economic data such as inflation, unemployment, gross domestic product (GDP) growth, productivity, and market returns.

An index shows the development of a number over time. It is not expressed in tons, euro or any similar common unit; it only shows the change of a figure from one point in time to another. For simplicity, the reference value, which may refer to a given year (base year), is usually set to 100.

An index chart is an interactive line chart that shows percentage changes for a collection of time-series based on a selected index point. In this example, we see the percentage change of selected stock prices ing to the day of purchase.
