Calculated Fields

Definition

Calculated fields are custom fields created in data analysis software that allow users to perform calculations on existing data to derive new insights. By utilizing formulas and expressions, these fields enable analysts to manipulate and combine data in ways that standard fields cannot, leading to more tailored reporting and decision-making.

5 Must Know Facts For Your Next Test

1. Calculated fields can include mathematical operations such as addition, subtraction, multiplication, and division to create new metrics from existing data.
2. They can also utilize functions like IF statements, DATE functions, and string manipulations to tailor analyses according to specific business needs.
3. In platforms like Tableau and Power BI, calculated fields can be created within the user interface, making them accessible even for non-technical users.
4. Using calculated fields enhances data storytelling by allowing analysts to focus on specific trends or patterns that are crucial for decision-making.
5. Changes made in the calculated field are automatically reflected across all visualizations using that field, ensuring consistency in reporting.

Review Questions
