Objective: To be able to draw bar charts
The dataLast night I stood on Fulwood road for 5 mins and counted
the different types of transport that passed me.I collected the results in a TALLY CHART.

Be able to construct a pie chart from a collection of data, using a protractor.
Make Toyota Ford Citroën Volvo
Frequency 3 2 4 1
Construct a pie chart to show this information.
A full circle is 360o
There are a total of 3+2+4+1 = 10 cars
We use 36o to represent each car
360o
Make Toyota Ford Citroën Volvo
Frequency 3 2 4 1
Angle in pie chart
We use 36o to represent each car so the3 Toyotas are represented by 3x36o = 108o
Work out the angle needed for each of the other models of car
3x36o
=108o
2x36o
=72o
4x36o
=144o
1x36o
=36o
Make Toyota Ford Citroën Volvo
Angle 108o 72o 144o 36o
Mark the centre of the pie and draw the circle.
Draw a line from the centre to the edge
Measure the first angle needed (108o)
Draw in the line and label the section
108oToyota
Make Toyota Ford Citroën Volvo
Angle 108o 72o 144o 36o
From this line measure the next angle, draw the line and label the section.
Continue in this way
Check that the last section has the correct angle and label it.
Toyota
Ford
Citroën
Volvo
Why do we use 36o to represent 1 car? What would happen if there were 20
cars? What about 60 cars? Or 15 cars?
If there were 20 cars in your survey, what angle would you use to represent 4 cars? 7 cars? 12 cars?
