What is the main purpose of the 'average' summary type in search results?

The purpose of the 'average' summary type in search results is to calculate the average amount for a specified column within the dataset. This means that when using the 'average' function, the system will sum all the values in the selected column and then divide that total by the number of entries, yielding the mean value. This can be particularly useful for analyzing sales data, expenses, or any numerical data where understanding the typical value is important for making informed business decisions.

The other summary types mentioned focus on different calculations, such as finding maximum and total values, which serve specific analytical needs but do not provide an average figure. Hence, each summary type has its unique purpose, with 'average' specifically targeting the calculation of mean values in the results presented.
