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

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.

To show the favourite games of Navya's classmates, a bar graph is the best choice. Here’s why:

• A bar graph uses bars to represent different categories, making it easy to compare the number of students who like each game.
• Each bar can show the number of students for cricket, hockey, and football clearly.
• This type of graph is simple to read and understand for everyone.

Other options, like a pictograph or pie chart, may not show the comparison as clearly as a bar graph does.

• Pictograph – also possible, but it is less precise for larger data.
• Line Graph – used for trends over time, not suitable here.
• Pie Chart – also represents proportions well, but with small numbers, a bar graph is simpler and clearer for students.

• 1 symbol = 5 students

• We have 25 students.

• To find the number of symbols, we divide: 25 ÷ 5 = 5

Answer: 5 symbols are needed to represent 25 students. 

Let’s solve step by step:

Books borrowed:
Monday = 25, Tuesday = 30, Wednesday = 28, Thursday = 35, Friday = 40

1. Least books borrowed → Monday (25)
2. Difference between Friday and Monday → 40 – 25 = 15

To find the number of students who obtained marks more than or equal to 5, we can count the marks that are 5 or higher from the given data:

Marks: 8, 6, 5, 5, 5, 9, 7, 8, 5, 8, 10, 8, 8, 9

Counting these, we find:

• 8: 6 times
• 6: 1 time
• 5: 4 times
• 9: 2 times
• 7: 2 times
• 10: 1 time

In total, there are 16 students who scored 5 or more marks.

In a bar graph, the height of the bar tells us the number (frequency).

• The bar for 3 members touches 40 on the y-axis.

• This means there are 40 families having 3 members.

On which day were the most pencils sold?

The highest number = 20 (Friday)
Most pencils were sold on Friday.

How many more pencils were sold on Friday than on Wednesday?

• Friday = 20

• Wednesday = 10

• Difference = 20 – 10 = 10

10 more pencils were sold on Friday than on Wednesday.

In a bar graph, the longest bar represents the largest number (highest frequency). Since Friday has the longest bar, it means the maximum number of books were borrowed on that day.

Data from survey:

• Apples = 8

• Bananas = 12

• Mangoes = 15

• Grapes = 10

Step 1: Find the most popular fruit

• Maximum number = 15 (Mangoes)

• Most popular fruit = Mangoes

Step 2: Find how many more students liked mangoes than apples

• Mangoes = 15

• Apples = 8

• Difference = 15 – 8 = 7

Answer: B: Mangoes, 7 more

The number of apples sold on Tuesday is represented by the 3 symbols. Since each symbol represents 4 apples, we can use the following calculation:

• Number of symbols = 3
• Number of apples per symbol = 4
• Total apples sold = 3 symbols × 4 apples/symbol = 12 apples

Thus, the correct answer is 12 apples.
