## 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.
4. Columns to represent how many of each.

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.

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.

• 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).
