How to make a Bar Graph

How to make a Bar Graph/Column Graph  

A graph is a visual representation of  data. Graphs are much easier to read for visual learners and learners that want a clear straight way of knowing there information. To make your very own bar graph read the following procedural text. You will make a simple graph.

Please Note

You will need some data before you start your graph to fill in the graph.

Materials Needed 

  • Coloured Pencils [if you would like to colour your graph in]
  • Ruler
  • A4 [or bigger if you want] piece of paper
  • Pencil

Method:

1. Firstly with your paper, pencil and ruler draw an L shape that has a horizontal line and a vertical line with a 90 degrees angle in the bottom left hand corner. Don’t make it to big just make sure you have some space around it to write on.

 

2. On the vertical line (y axis)number it from top to bottom and make sure they are evenly spaced. Start with 0 when numbering and number it to the number of votes you have. Make sure your numbers are evenly spaced.

 

 

3. On the horizontal line [x axis] your answers you told when you did the vote. Say the question was ‘what is your favourite animal’ the answers could be dog, cat, fish, pig, horse [you can have as many as you want. If you don’t have enough room just write 1,2,3,4 etc. and have a key saying

1=red

2=blue

3=green [this would be if your question was ‘what is your favourite colour’]

Or just write the questions.

4. Now we need to add the data to put in our graph. With your ruler on the horizontal line, draw a rectangle starting from the horizontal line and draw it to the number on the vertical line about how many people voted for that. Say you did a survey on what colour cars we going past and you saw 12 red ones then you would draw it up to the 12th number on the vertical line.

Make sure with every rectangle you do it should be the same width.

5. Do that with every answer. Now if you want colour it in and write a title or the question up the top. This is an example of a completed.

The data I made this graph into is as followed:

‘What is your favourite type of chocolate?’

Normal chocolate=2 people

Dark chocolate=1 people

White chocolate=4 people

Mint chocolate=8 people

Caramel chocolate=9 people

Strawberry chocolate=0 people
