What is the primary use of calculated fields in Tableau?

Calculated fields in Tableau are primarily used to create new data from existing fields. This functionality allows users to perform operations and transformations on their data directly within Tableau, enabling the creation of custom metrics, aggregations, or derived values that are not present in the original dataset.

For instance, a calculated field might be used to combine different fields (such as concatenating first and last names), apply mathematical calculations (like calculating profit by subtracting costs from revenue), or even implement logical statements (such as categorizing sales performance into bands). This flexibility is crucial for data analysis, as it enables analysts to derive insights that are specifically tailored to their analytical needs and objectives.

Other options do not align with the primary purpose of calculated fields. Inputting data manually is handled in a different part of the Tableau workspace and doesn't relate to the dynamic capabilities that calculated fields offer. Storing raw data is not the function of calculated fields; data sources importing and connecting to datasets serve this purpose. Visualization pertains to how data is displayed in Tableau, which is essential, but again, it is separate from the calculation aspect of fields. Thus, the fundamental role of calculated fields is to enhance data analysis through the generation of new insights.
