Statistics - Drawing and Interpreting Tables

 

Part 1:  Teaching

 

Statistics is the area of maths that involves gathering, recording and presenting data in a clear and helpful way.

Data is the word we use in maths to mean the information that we gather.

Data can be presented in different ways e.g. tally chart, table, pictogram, bar chart, line graph, pie chart and many more.

 

Remind yourself about these types of graph with this PowerPoint presentation:

Part 2:  Gather data and create table

 

Your task is to gather some data and create your own table.

What data shall I collect?

Think about some data that you can collect at home. Here are some ideas:

How many different birds visit your garden in 20 minutes?

How often does each number come up when you roll a die 50 times?

How many different colour/ type of sweet or chocolate are in a sweet packet (Jelly Babies/ Haribo/ Smarties etc.)?

How many squats can each member of your family do during a PE with Joe session?

How many houses on each of the roads near your house have a Rainbow poster in the window?

How many times do each of the vowels a, e, i, o and u appear in a paragraph of text from your reading book?

 

What should my table look like?

Once you have decided on the data you are collecting, you will need to create a table to record your data in. If you have squared or lined paper you may find it easier to create a neat table.

 

Key questions:

How many columns will you need?

How many rows will you need?

Have you written clear headings for your rows/ columns?

Have you given your table a title?

Will you use tallies?

How will you record your totals?

Here are some examples of clear, labelled tables. Use these to help you create your own:

Now you have created your table, you can gather your data.

 

Part 3:  Interpreting your table

 

What does my table tell me?

Once your table is complete, answer these questions:

 

What is your highest result?

What is your lowest result?

What is the range of your results?

(Remember: The range is the difference between the largest and smallest result)

What is the sum of all your results?  

(Remember: The sum of your results is all of them added together)

Are your results what you expected?

 

Can you create some questions of your own about the data in your table?

 

Extension:

Can you turn your table into a bar graph or pictogram? Use the template or squared paper to help. You could even do it on the computer if you are confident.

Don’t forget to use a suitable scale, axis labels, a title and a key where they are needed!

 

Here are some good examples:
