Pictograms and Bar Charts

Pictograms and bar charts are used to show data in a way that is easy to read.

Pictograms

A pictogram is a diagram like a table that shows the numbers as pictures.
A very simple pictogram will use one picture to represent one item.
Most pictograms use a picture to represent more than one item.

Bar charts

A bar (or column) chart is a useful way to show data.
Bar charts allow us to quickly compare data because we can see the height of the bars.
We can see immediately which is the tallest or shortest.

Sam's bar chart

Sam makes a bar chart from his data on teachers’ drinks.
He can see that tea is the most popular drink as it has the tallest bar.
- Sam’s scale goes up in 2s.
He wants to know how many more people want squash than hot chocolate.

Answer
