Which of the following is a common aggregation operation that computes a single value from a set of values?

Explanation:
Aggregation is the process of turning many values into one value. It’s the general idea of summarizing a set by combining its elements. The other options are specific ways to summarize data—sum adds all values, max picks the largest, and median finds the middle value. All of these are examples of aggregation, but the word that best names the overall operation of reducing a set to a single value is aggregation itself.
