Tableau Desktop Foundations Practice Question

The correct answer is to assign an alias. Aliases in Tableau are used to provide an alternative name for a specific value, or member, within a discrete dimension. This is the most direct way to correct misspellings or standardize names for display purposes without altering the underlying data. Renaming the data field would change the name of the entire 'Region' column, not the values within it. While creating a calculated field or grouping values can achieve a similar result, they are less direct. A calculated field requires writing a conditional expression, and grouping is typically used to combine multiple distinct members into a larger category, creating a new field.
