What is the primary purpose of Level of Detail (LOD) in dashboards?

The concept being tested is how Level of Detail controls where and how data is aggregated in a dashboard. LOD lets you define calculations at a specific level of granularity, independent of what dimensions are currently shown in the view. This is essential for getting stable and meaningful totals or averages when you filter, drill down, or add different levels of detail to the visualization. For instance, you might want the total sales per customer even if the chart is showing sales by product category; using an LOD expression fixes the aggregation level so the result remains consistent across different slices of the data. The other options describe usage metrics, data update timing, or visual styling, none of which address how the data is aggregated nitty-gritty-wise.
