Question:

## Which of the following is true of the LOOKUP function?

Solution:

• It is similar to vLOOKUP in Excel
• Duplicate values in the 2nd parameter (“keys”) are not a problem.
• The 1st and 2nd paramters need to evaluate to the same number of values
• The 2nd and 3rd parameters need to evaluate to the same number of records
• Formulas that use LOOKUP cannot be sorted
• LOOKUP looks into a long list of values (input); finds a match in a second list of values (keys), and, where there is a match, returns a corresponding value (values).
• LOOKUP looks into data with duplicate values (input); deduplicates the input records (keys), and returns a summarized value based on the deduplicated data.
