Test: Data Handling and Presentation - 1 - Class 6 MCQ

1. Pictograph

   • A pictograph uses symbols or images to represent data, with each symbol representing a certain number of items.
   • For Navya’s data, each image (e.g., a bat for cricket or a football) could represent 1 student or a group of students. This type of chart works well for younger audiences or when there are simple, small numbers.
   • However, it can be time-consuming to create symbols for each category and is less precise for comparison, especially with smaller differences in data.

2. Line Graph

   • A line graph displays data points connected by lines, typically used to show changes over time.
   • Since Navya’s data is categorical (different sports), a line graph would not be suitable here because it’s designed for data that shows trends or progression (like data over months or years).

3. Bar Graph

   • A bar graph uses bars of varying lengths to represent different categories, making it effective for comparing quantities across categories.
   • For Navya’s data, each game would have a bar with a height that represents the number of students who prefer that game. It’s simple and effective for comparing discrete categories like cricket, hockey, and football.

4. Pie Chart

   • A pie chart divides a circle into slices to represent parts of a whole, which can show proportions effectively.
   • For Navya’s data, each game would have a slice representing the percentage of students who prefer it. While it could work here, pie charts are most effective when there are a few large categories or when the focus is on understanding proportions rather than direct comparisons.

Conclusion: While a pie chart or pictograph could work, the bar graph is the most straightforward and effective choice for comparing these categorical preferences directly.

The total angle in a pie chart is 360 degrees. For 10 students, the angle is (10/30) * 360 = 120 degrees.

The shortest bar indicates the least quantity, so the fewest candies were sold on Monday.

The mode represents the most frequent response, so the fruit that is the mode will likely have the highest bar.
