Which measure type is typically used for calculation based on summed values?

• A. Aggregate measures
• B. Post-SQL measures
• C. Non-aggregate measures
• D. Calculated measures

Answer: (A)

Aggregate measures are specifically designed to perform calculations based on summed values. These measures summarize data across multiple records, allowing for operations such as counting, averaging, or summing, to be applied to groups of data points. In the context of Looker and LookML, aggregate measures are crucial in creating meaningful insights from large datasets by reducing the complexity of raw data into comprehensible metrics. In contrast, post-SQL measures operate after the SQL query has been executed, meaning they manipulate or calculate values that already exist in the result set, rather than driving aggregation at the database level. Non-aggregate measures provide individual data points without summation, and calculated measures allow custom calculations using existing fields but do not inherently imply aggregation. Therefore, when needing to work with summed values in analytical reporting, aggregate measures are the appropriate choice, reflecting the sum of numerical data in an efficient and logical manner.
