11-Plus Mathematics: Data Handling

Data Handling in 11-Plus Mathematics

Data handling is a crucial component of the 11-plus mathematics curriculum, focusing on the interpretation and creation of various data representations. This topic equips students with the skills to read and analyze information presented in tables, bar charts, pictograms, line graphs, and pie charts.

Understanding Data Formats

Students will learn to extract relevant information from different data formats:

• Tables: Organize data systematically, allowing for easy comparison and analysis.
• Bar Charts: Visual representations that use bars to show quantities for different categories, making it easy to compare values.
• Pictograms: Use images or symbols to represent data, providing a visual way to understand quantities.
• Line Graphs: Show trends over time, helping students analyze changes and patterns in data.
• Pie Charts: Illustrate proportions of a whole, allowing students to see how different parts relate to the total.

Skills Developed

Through this topic, students will develop the ability to:

• Read and interpret data accurately from various formats.
• Make comparisons between different sets of data.
• Answer questions based on the information presented in charts and tables.
• Create their own charts and graphs to represent data they have collected.

Practical Applications

Understanding data handling is not only essential for the 11-plus exam but also for real-life situations where data interpretation is necessary. Whether it's analyzing sports statistics, understanding survey results, or interpreting scientific data, these skills are invaluable.

Worked Example

Problem: The following table shows the number of books read by students in a month:

Question: Who read the most books?

Solution:

• Student A read 5 books.
• Student B read 3 books.
• Student C read 7 books.

Therefore, Student C read the most books.
