Pie Chart
Pie Chart
Pie Chart: Pie chart is a way of representing simple data for easy understanding. A pie chart consists of sectors of a circle. The size of each sector is directly perportional to the component part or information it represents.
Central angle for a component = (FREQUENCY/TOTAL FREQUENCY) 360
PIE CHART Construction:
Example: There are 216 workers in a factory as per list given below:
| Cadre | Labourer | Mechanic | Fitter | Supervisor | Clerk |
|---|---|---|---|---|---|
No. of Workers | 75 | 60 | 36 | 27 | 18 |
Represent the above data by a pie chart.Solution:Total number of workers = 216.
Calculation of Central Angles
| Cadre | No. of Workers | Central Angle |
|---|---|---|
Labourer | 75 | (75/216 × 360)° = 125° |
Mechanic | 60 | (60/216 × 360)° = 100° |
Fitter | 36 | (36/216 × 360)° = 60° |
Supervisor | 27 | (27/216 × 360)° = 45° |
Clerk | 18 | (18/216 × 360)° = 30° |
EXAMPLE:
Thus, we obtain the required pie chart, as shown in the given figure.
