In the 11+ Maths exam, questions on data handling are a certainty. Why? Because the ability to read, interpret, and analyse data is one of the most important real-world skills a child can learn. From reading a bus timetable to understanding a news report, we are surrounded by data every day.
For a child, these questions can seem intimidating. They are often presented as a large block of information – a complex chart or a dense table – and the pressure of the clock can make it difficult to know where to even begin.
The secret to success is to have a clear, systematic approach. At elevenplus.com, we teach children to become “data detectives,” equipped with a simple framework to confidently extract the right information and solve any problem.
This guide will break down the main types of data handling questions your child will face and provide a simple 3-step method to tackle them with accuracy and speed.
In this definitive guide, you will learn:
- How to interpret the 4 main types of charts and tables in the 11+.
- A simple 3-step method for solving any data handling question.
- A clear explanation of averages (mean, median, mode, and range).
- Expert tips to avoid the most common data handling pitfalls.
The 4 Key Types of Data Presentation
Your child needs to be fluent in reading these four common formats.
1. Tables and Timetables
These present information in rows and columns.
- The Key Skill: Carefully reading the row and column headings to find the specific piece of data where they intersect. For timetables, a common question involves calculating the duration between two times.

2. Bar Charts and Pictograms
These are used to compare amounts between different categories.
- The Key Skill: Reading the scale on the y-axis (the vertical axis) carefully. The bars often fall between the marked numbers, requiring careful interpretation. For pictograms, the most important step is to read the key to see what each symbol represents (e.g., one circle = 10 votes).
3. Line Graphs
These are used to show how something changes over time.
- The Key Skill: Tracking the line to see when it goes up (an increase), goes down (a decrease), or stays flat (no change). Questions often ask for the difference between the highest and lowest points.
4. Pie Charts
These are used to show parts of a whole.
- The Key Skill: Understanding that the entire circle represents 100% of the data. Questions often require a good knowledge of fractions, percentages, and angles (the whole circle is 360°).

The 3-Step Method to Solve Any Data Question
To avoid feeling overwhelmed, teach your child to use this simple, repeatable framework for every question.
- Read the Question First: Before even looking at the chart or table in detail, read the question carefully. Underline exactly what it is asking for. Are you looking for a total, a difference, or a specific value?
- Identify the Correct Data: Now, look at the chart or table. Use the underlined keywords from the question to locate the correct bar, row, column, or segment. Use your finger or a ruler to trace the lines to the correct values on the axes.
- Process the Information: The final step is to perform the necessary calculation. This might be a simple subtraction to find a difference, an addition to find a total, or ordering the values from smallest to largest.
By following this “Read, Identify, Process” method, your child can approach each question with a calm, logical plan.
Don’t Forget Your Averages!
A key part of data handling is understanding averages. Your child needs to know the difference between the four main types:
- Mean: The most common type of average. To find the mean, you add up all the values and divide by the number of values.
- Median: The middle value when all the numbers are placed in order from smallest to largest.
- Mode: The value that appears most often in a set of data.
- Range: The difference between the highest and lowest value in a set of data.
Expert Tips to Avoid Common Pitfalls
- Check the Scale: This is the most common trap in bar and line graphs. Always check what each increment on the axis is worth. Is it going up in 2s, 5s, 10s, or 100s?
- Read the Key: For pictograms and some complex charts, the key is the most important part of the puzzle. Ignoring it will lead to the wrong answer.
- Answer the Right Question: After doing a calculation, always do a final “Answer Box Double-Check.” Reread the question to make sure your answer is what was actually asked for.
Data handling is a skill that builds confidence and logical thinking. By mastering these formats and using a consistent method, your child can turn this potentially tricky area into a source of easy marks.
