# Handling data · Years 5–6

> Handling data, Years 5–6: Organising data, Bar charts, Pictograms and more. Explanation, worked examples and free practice for the national curriculum in England.

In Handling data (Years 5–6) you practise 4 skills: Organising data · Bar charts · Pictograms · Pie charts.

To put results in a table, count how many times each result appears. The result that appears most often is the most common one.

In a bar chart, the height of each bar shows how many there are. Read the height against the lines on the axis. A double bar chart has two bars for each group, and the key tells you what each kind of bar shows.

In a pictogram each picture is worth the number in the key. If each picture is worth 10, three pictures are 30 and half a picture is 5.

A pie chart shows how a whole is shared out. A sector that is half the pie is half of the votes; a sector whose corner at the centre is a right angle is a quarter; and when the pie is cut into eight equal parts, each part is an eighth.

**Tip:** Before you answer, read the title and the key: what is being counted, and what each picture or each line on the axis is worth.

## What you learn

### Organising data

- Example: Ten children said how many brothers and sisters they have. These are the answers: 3, 1, 2, 3, 3, 1, 1, 1, 3, 1 How many times does the number 1 appear in the list?
- Answer: 5
- Solution: These are all the times 1 appears: 1, 1, 1, 1, 1 The number 1 appears 5 times.

### Bar charts

- Example: The pupils in the year group chose their favourite fruit. (A bar chart: Apple, Banana, Grapes, Melon. The lines on the scale go up in steps of 2.) How many pupils chose apple?
- Answer: 10
- Solution: The bar for Apple reaches 10. The lines on the scale go up in steps of 2.

### Pictograms

- Example: The pictogram shows how many books were borrowed each day. (A pictogram. Each symbol is worth 10. Sunday: 8 symbols, Monday: 3 symbols, Tuesday: 5 symbols, Wednesday: 1 symbol.) How many books were borrowed on Tuesday?
- Answer: 50
- Solution: On Tuesday: 5 symbols. 5 × 10 = 50 On Tuesday, 50 books were borrowed.

### Pie charts

- Example: Every pupil in the class voted for a class representative. The pie chart shows how the votes were shared. (A pie chart with sectors for Ava, Jack, Isla and Oliver) Who got the most votes?
- Options: Isla · Jack · Oliver · Ava
- Answer: Oliver
- Solution: Oliver’s sector is the biggest in the pie.

The exercises are made by rules and the answers are worked out in code. The topic follows the national curriculum in England: mathematics (key stages 3 and 4).
