>> RACHEL : 

So today, I'm going to talk to you about data handling in football.

We use maths for handling data collected during games,

which is then used for making charts when we do match reports.

Charts are really useful

to display information in a visual way

so you can quickly see how things are going.

And we can use charts to compare teams

and help us understand who is doing well at any given time.

This is a bar chart.

It tells us how many matches six different teams have won so far.

Each bar represents a club

and the height of the bar lines up with a number on the left-hand side.

This number tells us how many matches a team has won.

So here, we can clearly see that Chelsea has won the most matches

because their bar is the tallest,

and we can check exactly how many matches they've won so far,

it's 26.

Liverpool here haven't won quite as many with 18 wins,

but all of these teams are still chasing the leaders

in a race to be crowned champions.

When we make a bar chart,

we need to make sure we include some important things.

The first one, a title,

this tells us what the chart is all about.

Then we have to label each axis so it's clear what each one means.

The horizontal axis on this chart tells us which clubs we're looking at

and the vertical one over here shows what we're counting,

which in this case is matches they've won.

Once we have collected all the data

and we know how many matches each club has won,

we can accurately draw their bars.

And it's easy to see how they compare with each other.

A good tip when you're making your own bar charts

is to always use a ruler when you're drawing your bars.

This keeps them neat and very easy to read.

And now it's time for you to create your very own bar chats,

so go, collect some data, and have a go.
