Which statement regarding the unique tool is true?

The unique tool in Alteryx is indeed case sensitive, which means that it differentiates between values based on their case. For example, "apple" and "Apple" would be considered two distinct values. This characteristic is essential when dealing with datasets that may have variations in case, as it ensures that all variations are accounted for correctly in the output.

Understanding the case sensitivity of the unique tool is crucial when performing data deduplication or when trying to keep unique entries based on specific criteria. Therefore, being aware of how case affects the uniqueness of values helps users to maintain data integrity and achieve accurate analysis results.
