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.

To find the angle of the football section in the pie chart, we can use the formula for calculating the angle of a section in a pie chart:

Given:

• Number of students liking football = 10
• Total number of students = 30

Now, substitute these values into the formula:

So, the angle representing the football section is 120 degrees.

Therefore, the correct answer is D: 120 degrees.

The frequency of a number is the number of times it appears in a set of data.

In this case, you rolled the dice 30 times, and the number 3 appeared 5 times.

So, the frequency of '3' is 5.

Therefore, the correct answer is B: 5.

If the bar graph shows the number of books borrowed from the library during the week, and Friday has the longest bar, this implies that most books were borrowed on Friday.

Therefore, the correct answer is A: Most books were borrowed on Friday.

To display the percentage of students who preferred different after-school activities, a Pie Chart would be the best option. A pie chart visually represents parts of a whole, showing the proportion of each category (like sports, music, reading, etc.) in a circle, with each slice representing a percentage of the total.

Therefore, the correct answer is C: Pie Chart.

The bar corresponding to 3 members reaches the height of 40 on the y-axis.

Thus, the number of families having 3 members is 40.

Therefore, the correct answer is (d) 40.

If each symbol represents 4 apples and there are 3 symbols next to Tuesday, the total number of apples sold on Tuesday can be calculated by multiplying the number of symbols by the number of apples each symbol represents:

3 × 4 = 12

Therefore, 12 apples were sold on Tuesday.

The correct answer is D: 12.

Given marks:

8, 1, 2, 6, 5, 5, 5, 0.1, 9, 7, 8, 0, 5, 8, 3, 0, 8, 10, 3, 4, 8, 7, 8, 9, 2, 0

Marks greater than or equal to 5:

8, 6, 5, 5, 5, 9, 7, 8, 5, 8, 8, 10, 8, 7, 8, 9

Count of marks greater than or equal to 5:

There are 16 students who obtained marks greater than or equal to 5.

The correct answer is (d) 16.

From the graph:

• Party A has the highest number of seats (more than 40).
• Party B has a lower number than Party A.
• Party C also has fewer seats than Party A.
• Party D has fewer seats than Party A.
• Party E has the fewest seats.

∴ The political party that won the maximum number of seats is A.

So, the correct answer is (a) A.
