True or False: In Visual Preview and with the Sorter, empty string values are always displayed at the top of attribute columns when sorted ascending.

• A. True
• B. False
• C. Not enough information
• D. Depends on data type.

Answer: (A)

When sorting strings in ascending order, the empty string is considered the smallest possible value. Visual Preview’s Sorter treats the attribute values as strings, so an empty value comes before any non-empty string. That’s why empty string values appear at the top of the column when sorted ascending. This behavior specifically applies to string-type data; if the attribute were a different type (like numeric), the ordering could be different.
