## 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).

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.

## Statistics – Analysing graphs

I am learning to analyse the results in a graph by answering questions.

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

Today you are going to be putting all your shoes into groups based on the main colour of them.

You will be organising your shoes in a different way to what you have previously done this week. This new way is called a bar graph.

You will be looking at this more closely in your WebEx classes next week.

Collect all of your shoes and group them into similar colours, look at the image below for a guide:

Take a photo or draw a picture of them.

1. What colour shoe do you have the most of?
2. What colour shoe do you have the least of?
3. Are there any colours that you have the same amount of?

Make sure to pack away your shoes when you have finished!

## Statistics – Tally marks

I am learning to record and analyse a tally graph of minibeasts.

I know I can do it when I have drawn and answered questions about my tally graph.

Yesterday you went on a mini-beast hunt for Integrated Studies. You explored outdoors to see if you could spot the following types of mini-beasts; bees, butterflies, snails, spiders and other.

You recorded your findings in a tally graph.

Using the tally graph that you created yesterday answer the following questions and record them underneath your graph.

1. What was the most popular mini beast you found?
2. Were there any mini beasts that you didn’t see and record, if so, what?
3. How many bees did you find?
4. How many mini beasts did you find altogether?

## Statistics – Tally marks

I am learning to categorise and record my toys using tally marks.

I know I can do it when I have put my toys into categories and recorded how many of each using tally marks.

There are many ways you can record data. Over the next 2 weeks you will be learning about a few of the different types.

Today we are focussing on recording data with tally marks.

You have already looked at tally marks at school, watch this video below to help refresh your memory.

Now that you have an idea of how to record a tally graph you are going to use this skill to categorise and record your own toy tally graph.

Categorising means that you put things into groups based on characteristics that they have. For example, you might categorise based on colour, size or shape.
