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.

What we have learnt
- Data is the information collected and organized for analysis.
- Graphs like pictographs, bar graphs, and pie charts provide visual representation of data.
- Probability helps understand the likelihood of outcomes in random experiments.
Key Concepts
- -- Data
- Pieces of information representing the parameters or aspects of a context being studied.
- -- Pictograph
- A visual representation of data using pictures or symbols where each symbol represents a certain number of items.
- -- Bar Graph
- A chart that presents categorical data with rectangular bars, where the lengths of the bars are proportional to the values they represent.
- -- Pie Chart
- A circular statistical graphic divided into slices to illustrate numerical proportions.
- -- Probability
- The measure of the likelihood that an event will occur, expressed as a ratio of favorable outcomes to the total outcomes.
