Tableau Desktop Foundations Practice Question

The correct formula is [First Name] + " " + [Last Name]. In Tableau, the plus (+) operator is used to concatenate (combine) string values. To add a literal space between the first and last names, the space character must be enclosed in quotes and included in the calculation.

The formula [First Name] + [Last Name] is incorrect as it will combine the strings without a space, resulting in a format like 'JohnSmith'. The ampersand (&) operator is used for concatenation in other applications like Power BI, not Tableau. While Tableau has many built-in string functions, CONCATENATE() is not the standard operator for this simple arithmetic, and the plus (+) operator is the correct choice.
