How to explain which bar graph is correct? in bar charts to your child: Example question
31 October 2026

Bar graphs are a simple way for children to see information clearly. When your child is faced with more than one graph, it's important they know how to check which one matches the data given.

Example question
Here are two bar graphs showing the number of books read by children in a week.
Graph A shows: - Alice: 4 books - Ben: 6 books - Cara: 3 books
Graph B shows: - Alice: 4 books - Ben: 5 books - Cara: 3 books
Which bar graph is correct?
Step 1: Look at the data given
The numbers of books read are: Alice 4, Ben 6, Cara 3.
Step 2: Check each bar in the graphs
- In Graph A, Ben's bar shows 6 books.
- In Graph B, Ben's bar shows 5 books.
Step 3: Compare the bars to the data
Graph A matches the data for all children. Graph B shows the wrong number for Ben.
Answer
Graph A is correct because all the bars match the numbers of books read.
After working through this example, your child will be able to spot which bar graph is correct by comparing the numbers in the question with the bars shown. They can now try similar questions to build confidence with bar charts.
