What types of values can be allowed in numerical columns with a summer average grouping function applied?

The selection of both negative and positive values as permissible in numerical columns with a summer average grouping function is based on how averages are calculated. The summer average function computes the mean of all included values within a specified context, which allows for a range of inputs.

In practical terms, when you apply a summer average grouping function, all numerical values—including negative, positive, and zero—are considered in the calculation. This feature enables a comprehensive analysis across diverse data sets, which is essential for gaining insights into performance metrics, financial figures, or any other numerical data that might include losses (represented as negative values) alongside gains (positive values). Hence, the correct option captures the inclusive nature of numerical data processing when calculating averages.

This understanding is key for anyone working with data analytics or reporting, as it influences how outcomes are interpreted and decisions are made based on the analysis.
