Create and Interpret Column Graphs I

Lesson

A column graph is a graph used to display data about different groups. There are all different types of groups that can be looked at. For example the number of different types of bugs in a garden, the number of people with certain eye colours in a class or even the flavours of juice people prefer. 

Let's look now at how to create and interpret (understand) column graphs.

 

Creating a column graph

Let's say I looked in my garden and I found $6$6 ants, $5$5 worms, $3$3 caterpillars, $1$1 butterfly and $4$4 bees. Watch this video to see how we'd turn this into a column graph.

 

Interpreting a column graph

So what information can we get from a column graph? Let's watch another video and see.

Remember!
  • Give your graph a heading.
  • Label both axes (arms) of the graph.
  • Make sure the columns are equal widths and equally spaced.
  • Make sure that the height of the column matches the frequency (how often that score occurred).

Worked Examples

Question 1

The table below shows the house points earned by four colour houses at their swimming carnival.

House Points
Blue $60$60
Green $20$20
Yellow $70$70
Orange $60$60
  1. Complete the graph using the information from the table.

Question 2

The fish shop has $5$5 tanks.

The graph below shows the number of fish in the $5$5 tanks.

  1. Turn this information into a scaled bar graph.

Question 3

A dice is rolled and the number of times it landed on the digits 1-6 is recorded in the table below.

Dice Number Number of Rolls
1 $6$6
2 $4$4
3 $1$1
4 $8$8
5 $5$5
6 $7$7
  1. Complete the graph using the information from the table.
