Test: Data Handling and Presentation - 2 - Class 6 MCQ

The width of a bar in a bar graph does not represent any specific value. Instead, it is the length or height of the bar that indicates the frequency or quantity of the data being represented.

Key points to understand:

• The width of the bars is typically uniform across the graph.
• It is the length or height that shows the data's frequency or amount.
• Uniform spacing between bars indicates they represent distinct categories.

In summary, while the width is consistent, it is the bar's length or height that conveys the essential information in a bar graph.

Given: One scooter = 6 scooters

So total sold scooters = (Number of scooters) × 6

• Monday = 5 × 6 = 30
• Tuesday = 4 × 6 = 24
• Wednesday = 3 × 6 = 18
• Thursday = 5 × 6 = 30
• Friday = 7 × 6 = 42
• Saturday = 2 × 6 = 12

Hence, maximum scooters were sold on Friday.

Answer: B

To represent data on the number of pets owned by students in different grades, the most suitable type of graph would be a Bar Graph.

Here's why: A Bar Graph is ideal for comparing quantities across different categories, like the number of pets owned by students in each grade. Each grade can be represented as a category on the x-axis, and the number of pets can be represented on the y-axis.

Thus, the correct answer is B: Bar Graph.

To answer the question "Representation of data in tabular form is done by using _______", we can follow these steps:

Understanding the Question: The question asks for the method used to represent data in a tabular format. We need to identify the correct term from the options provided.

Analyzing Each Option:
- Bar graph: This is a graphical representation of data, not specifically a tabular form.
- Frequency: This refers to the number of times a particular value occurs, but it is not a method of representation itself.
- Tally marks: This is a method used to count and represent data in a simple and organized way, often used in tables.
- None of these: This option implies that none of the above methods are correct.

Identifying the Correct Answer: Since tally marks are commonly used to represent data in a tabular format, we conclude that the correct answer is tally marks.

Representation of data in tabular form is done by using tally marks.

The number '15' repeats 3 times in the given data: 18, 13, 15, 13, 18, 14, 15, 13, 14, 15.

So, the correct answer is: C: 3

The month with the maximum rainfall is August, which has the tallest bar.
Thus, the correct answer is: B: August.

In the given data: 1, 1, 2, 2, 3, 3, 4, 4, 2, 2, 3

The number 2 appears 4 times.

So, the frequency of 2 is: 4

Marks in English (from graph) = 15
Marks in Hindi (from graph) = 10
Marks in Maths (from graph) = 30
Marks in Science (from graph) = 20
Marks in S.St (from graph) = 25

Highest Mark are scored in Maths (30)

If  represents 5 eggs, then represents 4 times 5 eggs.

So, = 4 × 5 = 20 eggs.

The correct answer is: C) 20

On Tuesday:

• Number of bulb symbols = 8.
• Since each symbol equals 2 bulbs: Total bulbs sold on Tuesday=8×2=16.
