Q1. Which of the following is an example of primary data?
A) Population data published in a newspaper
B) Rainfall data collected by the weather department
C) Marks collected directly by a teacher from students
D) Data copied from a magazine
Answer: Marks collected directly by a teacher from students
Useful Concept for this Question
Primary data is collected directly by the person conducting the survey or study.
Concept Behind This Question
Students should distinguish between primary and secondary data.
Step-by-Step Solution
When a teacher collects marks directly from students, the information is collected firsthand.
Hence, it is primary data.
Therefore, the correct answer is:
Marks collected directly by a teacher from students
Exam Tip
Primary = Collected first-hand
Secondary = Obtained from existing sources
Q2. Which type of graph is most suitable for comparing the number of students in different classes?
A) Bar graph
B) Triangle
C) Circle
D) Straight line
Answer: Bar graph
Useful Concept for this Question
Bar graphs are used to compare quantities belonging to different categories.
Concept Behind This Question
Students should identify the correct graph for comparison.
Step-by-Step Solution
Each class is a separate category.
A bar graph compares these categories clearly.
Therefore, the correct answer is:
Bar graph
Exam Tip
Whenever the question asks for comparison, think of a bar graph.
Q3. A pictograph uses 1 symbol = 8 flowers. If there are 5 symbols, how many flowers are represented?
A) $$32$$
B) $$35$$
C) $$40$$
D) $$45$$
Answer: $$40$$
Useful Formula for this Question
$$\text{Total Items}=\text{Number of Symbols}\times\text{Value of One Symbol}$$
Concept Behind This Question
Students should correctly apply the pictograph key.
Step-by-Step Solution
One symbol = $$8$$ flowers
Number of symbols = $$5$$
$$5\times8=40$$
Therefore, the correct answer is:
$$40$$ flowers
Exam Tip
Always multiply the number of symbols by the value given in the key.
Q4. Which of the following statements is true about tally marks?
A) Every sixth tally crosses the previous five.
B) Every fifth tally crosses the previous four.
C) Tally marks are written only in pairs.
D) Tally marks are used only in graphs.
Answer: Every fifth tally crosses the previous four.
Useful Concept for this Question
Tally marks are grouped in sets of five for easy counting.
Concept Behind This Question
Students should know the correct method of writing tally marks.
Step-by-Step Solution
The first four tally marks are drawn vertically.
The fifth tally mark is drawn across the previous four.
Therefore, the correct answer is:
Every fifth tally crosses the previous four.
Exam Tip
One complete tally group always represents 5.
Q5. Which of the following statements is correct?
A) Frequency can never be zero.
B) A bar graph can compare different categories of data.
C) A pictograph does not require a key.
D) Raw data is always arranged in order.
Answer: A bar graph can compare different categories of data.
Useful Concept for this Question
Bar graphs help compare quantities from different categories.
Concept Behind This Question
Students should identify the correct statement related to Data Handling.
Step-by-Step Solution
- Frequency can sometimes be zero.
- Every pictograph requires a key.
- Raw data is generally unorganized.
- Bar graphs are used to compare categories.
Therefore, the correct answer is:
A bar graph can compare different categories of data.
Exam Tip
Read every statement carefully in concept-based MCQs.
Important Formulas & Concepts
1. Frequency
Frequency = Number of times an observation occurs
2. Pictograph Formula
$$\text{Total Items}=\text{Number of Symbols}\times\text{Value of One Symbol}$$
3. Tally Marks
The fifth tally mark crosses the previous four tally marks.
4. Primary Data
Primary data is collected directly from the original source.
5. Bar Graph
- Used to compare different categories.
- Bars should have equal width.
- Equal spacing should be maintained.
- Height of the bar represents the value or frequency.
FAQs
1. What is primary data?
Primary data is collected directly from the original source.
2. Why do we use a bar graph?
To compare quantities of different categories.
3. Why is a key necessary in a pictograph?
It explains the value represented by each symbol.
4. How many tally marks make one complete group?
Five tally marks.
5. What does frequency represent?
It represents the number of times an observation occurs.
Common Mistakes
❌ Confusing primary data with secondary data.
❌ Forgetting to use the pictograph key.
❌ Counting tally marks incorrectly.
❌ Drawing unequal-width bars.
❌ Assuming raw data is already organized.
Quick Revision Notes
✔ Primary data is collected directly.
✔ Frequency means the number of occurrences.
✔ One complete tally group represents 5.
✔ Bar graphs compare different categories.
✔ Pictographs always include a key.
✔ Equal-width bars improve graph accuracy.
✔ Organized data is easier to interpret than raw data.
Conclusion
Data Handling is an important chapter that enables students to organize and analyze information effectively. Understanding primary data, frequency tables, tally marks, pictographs, and bar graphs helps students solve real-life problems with confidence. Regular MCQ practice strengthens conceptual understanding, improves logical thinking, and prepares students for school and competitive examinations.
