Statistics – Bar graphs

I am learning to create my own bar graph.

I know I can do it when I have converted results into a bar graph.

Yesterday you were looking at a bar graph and learnt how to read the information on it. Today you will be extending on that skill further by having a go at drawing your own bar graph.

Some things you need to think about when creating your own bar graph include:

  1. An L shape for your graph to be on.
  2. Numbers up the side starting at the bottom and counting up.
  3. Your answers/choices listed along the bottom.
  4. Columns to represent how many of each.

Watch the following video to learn more about making a bar graph:

You will be using the following information to create your own bar graph in your scrapbook.

You may find it easier to use a ruler to rule the lines on your graph.

Students in Year One were asked the question ‘what is your favourite minibeast?’

There were 4 answers to choose from; bees, butterflies, snails, or spiders.

Below are their answers:

MinibeastCount
Bees4
Butterflies11
Snails6
Spiders8

From the information above you are going to turn it into a bar graph.

You want to begin your bar graph with an L shape like below.

You can then add your numbers from 0 to11 up the side and your 4 minibeast choices along the bottom.

Once you have completed your bar graph answer the following questions:

  • Which minibeast was the most popular?
  • Which minibeast was the least popular?
  • How many people liked bees and spiders (count both)?
