**Ans. Aggregate scores are calculated by finding the sum of all those subjects whose marks have to be considered, and then dividing the sum by total marks. The final result is then multiplied with 100, which gives the aggregate percentage.**

## How to Aggregate Percentages?

Aggregating percentages is an important skill to have when dealing with large datasets. It can help to quickly summarize a large amount of data and help to identify trends and patterns. There are a few different ways to aggregate percentages, depending on the data you are dealing with.

The first and most simple way is to add all the percentages together. This is the most straightforward approach, but it does not provide much insight into the underlying data. Adding all the percentages together will simply give you a total percentage, which may not be too useful in some cases.

The second method is to calculate the average percentage. This method is more useful in cases where the data is more evenly distributed. For example, if you are dealing with a dataset containing the percentage of votes each candidate received in an election, calculating the average percentage can give you a better idea of how the population voted overall.

The third method is to calculate the median percentage. This method is useful when dealing with data that is not evenly distributed, such as when dealing with income data. The median percentage will tell you what percentage of the population is in the middle of the income range. This can help to identify potential outliers and help to identify trends in the data.
