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)?

Statistics – Bar graphs

I am learning to analyse results on a bar graph.

I know I can do it when I have answered questions from a bar graph.

This week we will be looking at other types of graphs including bar graphs and pictographs.

Today’s focus is on bar graphs. These types of graphs are used to record data for questions that could have many answers.

Unlike a tally graph which records across the page, a bar graph will typically record up the page starting at the bottom.

A bar graph needs:

  • A title at the top (what the question is)
  • Labels along the bottom (the answers)
  • Numbers up the sides and columns (how many of each answer).

Watch the following video to learn more about bar graphs:

Independent Task

Look at the following bar graph which has asked the question ‘what is your favourite flavour of ice cream?’

Copy the graph by drawing it into your scrapbook.

Write 3 sentences about what information the bar graph tells us.

An example of a sentence may be ‘Rainbow flavoured ice cream is the most popular choice with 8 people saying it was their favourite.’

When writing your sentences remember to begin each sentence with a capital letter and end with punctuation.
