five simple rules for creating world-changing presentations.10

BAR GRAPH

The first rule is: Treat your audience as king.11

BAR GRAPHIt uses bars of different lengths and of equal widths to show the frequencies of the classes.It is used to show relationships between groups.The two items being compared do not need to affect each other.It is a fast way to show big differences.

Look at the way a bar chart is constructed. Can you name its different parts?

What goes here?What is this called?

What do we call this?

What is this?

A bar graph always has a TITLEVertical axis (y). Always labelled and numbered

Horizontal axis (x). Always labelled.

The height of the bars show frequencies recorded.

Can you read the answers?What does this bar chart show?How many students were surveyed?Which is the favourite movie?Which is the least liked?What intervals are used on the y axis?What intervals could you use if twice as many students were surveyed? Number of studentsMovie

How can you collect the information needed to construct a bar chart? By making a tally chart first!
