Q1. Which of the following is the first step in Data Handling?
A) Drawing a bar graph
B) Collecting data
C) Finding the average
D) Drawing a circle
Answer: Collecting data
Useful Concept for this Question
Data handling always begins with collecting information.
Concept Behind This Question
Students should understand the sequence of data handling.
Step-by-Step Solution
Before organizing or representing information, we must first collect it.
The collected information is called data.
Therefore, the correct answer is:
Collecting data
Exam Tip
Always remember:
Collect → Organize → Represent → Interpret
Q2. What is the frequency of an observation?
A) The size of the graph
B) The number of times an observation occurs
C) The total number of graphs
D) The number of symbols
Answer: The number of times an observation occurs
Useful Formula for this Question
Frequency = Number of occurrences of an observation
Concept Behind This Question
Students should understand the meaning of frequency.
Step-by-Step Solution
If a value appears several times in a data set, the total number of times it appears is called its frequency.
Therefore, the correct answer is:
The number of times an observation occurs
Exam Tip
Frequency simply means “how many times”.
Q3. Which representation uses pictures or symbols to show data?
A) Table
B) Pictograph
C) Line segment
D) Histogram
Answer: Pictograph
Useful Concept for this Question
A pictograph represents information using pictures or symbols with a fixed key.
Concept Behind This Question
Students should identify different methods of representing data.
Step-by-Step Solution
A pictograph displays data visually by using symbols or pictures.
The value of each picture is explained through a key.
Therefore, the correct answer is:
Pictograph
Exam Tip
Always check the key before solving pictograph questions.
Q4. Which graph is commonly used to compare different categories of data?
A) Circle
B) Bar graph
C) Triangle
D) Rectangle
Answer: Bar graph
Useful Concept for this Question
A bar graph compares quantities belonging to different categories.
Concept Behind This Question
Students should identify the appropriate graph for comparison.
Step-by-Step Solution
Different categories such as classes, fruits, books, or sports scores are best compared using bars of equal width.
Therefore, the correct answer is:
Bar graph
Exam Tip
Bar graphs are mainly used for comparison.
Q5. Before reading values from a bar graph, you should first check:
A) The graph scale
B) The notebook cover
C) The page number
D) The chapter number
Answer: The graph scale
Useful Concept for this Question
The scale tells the value represented by each division on the graph.
Concept Behind This Question
Students should know how to read graphs correctly.
Step-by-Step Solution
Reading the scale helps determine the exact value of each bar.
Ignoring the scale may lead to incorrect answers.
Therefore, the correct answer is:
The graph scale
Exam Tip
Always read the title and scale before interpreting any graph.
Important Formulas & Concepts
1. Frequency
Frequency means the number of times a particular observation occurs.
2. Tally Marks
Every fifth tally mark is drawn across the previous four tally marks.
Example:
|||| = 4
||||/ = 5
3. Pictograph
A pictograph uses pictures or symbols to represent data.
Always check the key before solving questions.
4. Bar Graph
A bar graph represents data using rectangular bars of equal width.
The height of each bar represents the frequency.
5. Interpretation of Data
Compare values carefully.
Find the highest value.
Find the lowest value.
Calculate differences whenever required.
FAQs
1. What is Data Handling?
