What
are the different ways to present data?
This
week we are going to revise our knowledge of how to use bar charts, pictograms
and tables.
What
does the data tell us? Let’s find out!
You will be best using lined paper to help you draw the
charts and tables out evenly.
The information in the data below tells how a Year 4 class
travels to school.
Look at the y axis, this one below is labelled Number of
Children. What is the scale used here? (Note that it goes up in twos to
16.) Be sure that you are using the
lines on the paper to guide you, so that your scale is also even, as should be
your bars along the x axis
showing
the different modes of Transport:
Have a go at changing this pictogram and the
table below into bar charts. Look
below to remind you how to draw it on your page. Don’t worry if you don’t have squared paper,
it’s easier, but you can still use lined.
First,
put your x axis (horizontal)
along the bottom of each chart, the y axis is vertical (which means going up).
Put a 0 where these two lines
meet.
Draw your first one, as the picture above. Now think about what scale
your y axis should be. How many does one green square represent?
Look at the highest amount, then can you divide it to create the appropriate
scales?
For the second bar
chart, look at the multiples of these numbers.
What is the highest multiple of 5 shown here?
This is the highest number your y axis should go to, or no more than 90.
