what types of functions might you use for looking items up within your data? can you list any examples of where the formulas you chose might be useful?
Tip: Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself. For example, you might use the MATCH function to provide a value for the row_num argument of the INDEX function.
The MATCH Function. The MATCH function looks up a value in a row or column and returns the relative position of the item. That is, if the item is the fourth position in the list (the lookup_array below), then MATCH returns the value 4. The function takes this form: =MATCH(lookup_value, lookup_array, match_type)
