THINK, DISCUSS AND WRITE
Question:
Which form of graph would be appropriate to display the following data?
Discussion:
For showing data that changes over a period of time, like production per year, a bar chart or a line graph is usually the best choice. They make it easy to see trends and compare values from year to year.
A pie chart is used to show parts of a whole. While we can create one for this data, it answers a different question: "What percentage of the total production (from 2001-2006) occurred in each specific year?".
Production of Food Grains
| Year | Production (in lakh tons) | Angle (for Pie Chart) |
|---|---|---|
| Total | 360° |
How is the angle calculated?
Angle = (Year's Production / Total Production) × 360°
Production Trend (Bar Graph)
Production Distribution (Pie Chart)
