Narnia Bar Charts
LO: to solve a problem by organising and interpreting
data in 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.
How can we collect the information we need to construct
a bar chart?
Make a frequency chart!
A frequency chart is similar to a tally chart…except you just write the
number instead of recording by tally!
