Question

Graph most suitable to show relation between price and production of an agricultural commodity is -

• A. Pie graph
• B. Pictorial graph
• C. Area graph
• D. Line graph

Hint:

Use line graphs to show continuous trends or relationships between two numeric variables (like price vs. production), and use bar or column charts to compare discrete categories.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Data visualization involves using graphical representations to present complex datasets clearly and effectively.
The choice of graph depends on the nature of the data and the specific relationship the researcher wants to demonstrate.

Step 2: Detailed Explanation:
Let us analyze the suitability of different graph types to show the relationship between price and production:
- Pie Graph (A): Used to show proportion or percentage contributions of different parts to a single whole (such as the market share of different crops). It cannot show relationships between two continuous variables.
- Pictorial Graph (B): Uses icons or images to represent data quantities (such as using tractor icons to show tractor sales). It is a simple tool used for general audiences but cannot display complex mathematical relationships.
- Area Graph (C): Similar to a line graph, but the area below the line is filled with color to show cumulative totals over time. It is not designed to show correlation between two variables.
- Line Graph (D): Highly suitable for showing relationships and trends between two continuous variables, such as price (on the Y-axis) and production (on the X-axis), or showing how both variables change together over a period of time.
A line graph can clearly show negative correlation—such as the law of demand, where higher production often correlates with a decrease in price.

Step 3: Final Answer:
The line graph is the most suitable graphical format to depict the relationship between price and production.
