Steps of construction of pie chart for a given data:
● Find the central angle for each component using the formula given on the previous page.
● Draw a circle of any radius.
● Draw a horizontal radius
● Starting with the horizontal radius, draw radii, making central angles corresponding to the values of respective components.
● Repeat the process for all the components of the given data.
● These radii divide the whole circle into various sectors.
● Now, shade the sectors with different colours to denote various components.
● Thus, we obtain the required pie chart.
☆The angle at the centre corresponding to the particular observation component is given by
[Value of the component / Total value] ×360
