Final answer:
The function not related to Lookup or Reference is FIND. VLOOKUP, INDEX, and MATCH are all Lookup and Reference functions that help search and retrieve data within a table or range, while FIND is a text function that locates the position of a substring in a text string.
Step-by-step explanation:
The function that is NOT a Lookup or Reference function in the list provided is C) FIND. The Lookup and Reference functions in Excel are designed to search for specific data within a dataset. VLOOKUP searches for a value in the first column of a table and returns a value in the same row from a specified column. INDEX returns the value of a specified cell or array element from within a table or range. MATCH searches for a specified item in a range of cells and then returns the relative position of that item.
On the other hand, FIND is a text function. It is used to locate the position of a substring within a text string, and it is case-sensitive. This function is not used to look up or reference data between arrays, tables, or ranges, which distinguishes it from the Lookup and Reference functions like VLOOKUP, INDEX, and MATCH.
