WALT – interpret data using bar charts

What do we know about bar charts already?

We know a bar chart should: have a title. have numbered and labelled axis. have clear bars showing how much of something has been observed/recorded. be numbered with sensible intervals. answer questions about the data.

Horizontal axis (x). Always labelled. Vertical axis (y). Always labelled and numbered. A bar chart always has a title. The height of the bars show how many of something was scored/recorded. It might also have a ‘legend’. This shows what the colour of each bar represents.

A Bar Chart to show children’s favourite toys. Go-go Hamster He-manTransformersSpace Hopper Ben 10MarblesBMXLego Favourite toy Number of children x y y

Looking at the bar chart, answer the following questions... 1.Which is the most popular toy? 2.How many children chose go-go hamster as their favourite toy? 3.Which is the least popular toy? 4.How many children altogether chose Ben 10 and transformers as their favourite toys?
