In USQL, which function would you use to calculate the average of a set of values?

In USQL, the function used to calculate the average of a set of values is the AVG function. This function totals all the values in a specified dataset and then divides that total by the number of values, providing a precise measurement of the central tendency within the data set.

Using AVG is particularly useful when you want to understand the mean value in a collection of numerical data, which can give insights into trends, performance metrics, or other relevant statistical analysis.

Other functions, such as SUM, provide the total of the values, while MEDIAN offers the middle value in a sorted list, and COUNT simply tallies how many values exist in a given dataset, but none of these directly computes the average like AVG does. Therefore, AVG is the specific function designed for calculating means in USQL.
