indexvalue
An index value is a numerical representation that indicates the relative position or magnitude of a particular item within a larger ordered set. It is often used in computer science, mathematics, and statistics to identify and access specific elements. In programming, for example, array elements are typically accessed using an index value, where the first element is often assigned an index of 0, the second an index of 1, and so on. This sequential numbering allows for efficient retrieval and manipulation of data.
In statistical contexts, an index value can be used to track changes in a variable over time
