Aggregation is the process of combining multiple items or data points into a single group or summary. For example, in statistics, you might aggregate data from different sources to find an overall average. This helps simplify complex information, making it easier to analyze and understand trends. In everyday life, aggregation can be seen in social media platforms like Facebook or Instagram, where posts from various users are collected into a single feed. This allows users to see a wide range of content in one place, enhancing their experience and keeping them engaged with the platform.
