Question

The following data shows the number of students in different streams in a school: 

Which type of graph is best suited to represent this data?

• A. Bar Graph
• B. Pie Chart
• C. Line Graph
• D. None of them

Hint:

Bar Graphs are best for comparing discrete data across different categories.

Answer 1

The Correct Option is A

To determine which type of graph is best suited to represent the data showing the number of students in different streams in a school, we must consider the characteristics of various graph types:

• Bar Graph: Ideal for comparing discrete categories of data. Each bar represents a category, allowing clear visualization of differences in quantities.
• Pie Chart: Suitable for showing proportions of a whole. Each slice represents a category, illustrating its relative size compared to the total.
• Line Graph: Best for displaying trends over a continuous interval or time period. Not appropriate for discrete categories without a meaningful sequence.
• None of them: Applicable when none of the standard graphs appropriately represents the data.

Given the data involves discrete categories (different streams) and we wish to compare the number of students in each, a Bar Graph is most appropriate. It allows clear comparison of student numbers across various streams.

Answer 2

To solve the problem, we need to understand the nature of the data and select the most appropriate graph type for clear representation.

1. Understanding the Concepts:

- Data Type: The data shows the number of students in different streams (Science, Commerce, Arts).
- Purpose: To compare quantities across different categories.
- Common Graph Types for Such Data: Bar graph, Pie chart, Column graph.

2. Given Data:

Stream	Number of Students
Science	120
Commerce	80
Arts	100

3. Selecting the Best Graph:

- A bar graph or column graph is best for comparing the number of students across streams as it clearly shows differences in quantities.
- A pie chart is also suitable if you want to show the proportion of each stream relative to the total.
- Since the question asks for the best suited graph, a bar graph is typically preferred for clarity and easy comparison.

Final Answer:

The bar graph is best suited to represent this data, as it clearly shows the comparison of the number of students in different streams.
