An analyst needs a field that returns "Profitable" when Profit is greater than zero and "Unprofitable" otherwise. Which calculated field expression is correct?

選択肢

1. IF [Profit] > 0 THEN "Profitable" (no ELSE, no END), because Tableau closes the expression automatically at the end of the line
2. SUM(IF [Profit] THEN "Profitable")
3. IF SUM([Profit]) > 0 THEN "Profitable" ELSE "Unprofitable" END
4. CASE [Profit] WHEN > 0 THEN "Profitable" END
