4. Data Handling

Data is essential in organizing and interpreting information for various contexts, whether in sports statistics, academic performance, or personal preferences. Visual representations such as pictographs, bar graphs, and pie charts play a crucial role in simplifying the comprehension of complex data. Understanding the basis of probability and its relation to real-world scenarios also helps in making informed decisions based on data-driven insights.
