Data Handling — MCQ Questions
1A teacher asks 30 students about their favourite fruit. This is an example of:
Show Answer+
Answer: Collection of data
Hint: When we gather information by asking questions or conducting surveys, what step of data handling is that?
Solution:
When a teacher asks students about their favourite fruit, she is gathering raw information.
Gathering raw information from a source is called collection of data.
2In a tally chart, the symbol |||| (four vertical lines with a diagonal line through them) represents which number?
Show Answer+
Answer: 5
Hint: We draw four vertical lines and then cross them with a fifth diagonal line to make counting easier.
Solution:
In the tally system, we group marks in bundles of 5.
Four vertical lines crossed by one diagonal line represents 5. — |||| = 5
3The marks obtained by 5 students in a maths test are: 8, 6, 7, 9, 5. What is the range of the data?
Show Answer+
Answer: 4
Hint: Range = Highest value - Lowest value.
Solution:
Arrange the data: 5, 6, 7, 8, 9.
Highest value = 9 and Lowest value = 5.
Calculate the range: — Range = 9 - 5 = 4
4Find the mean of the numbers: 4, 6, 8, 10, 12.
Show Answer+
Answer: 8
Hint: Mean = Sum of all observations / Number of observations.
Solution:
Sum of all observations: — 4 + 6 + 8 + 10 + 12 = 40
Number of observations = 5.
Calculate the mean: — Mean = 40 / 5 = 8
5In a pictograph, one symbol of a cricket bat represents 10 runs. How many runs are shown by 3 symbols?
Show Answer+
Answer: 30
Hint: Multiply the number of symbols by the value each symbol represents.
Solution:
Each symbol represents 10 runs.
Number of symbols = 3.
Total runs: — 3 x 10 = 30 runs
6The mode of the data set 3, 5, 7, 5, 9, 5, 2 is:
Show Answer+
Answer: 5
Hint: The mode is the value that appears most frequently in a data set.
Solution:
Count the frequency of each value: 2 appears 1 time, 3 appears 1 time, 5 appears 3 times, 7 appears 1 time, 9 appears 1 time.
The value 5 appears most often (3 times), so mode = 5.
7A bar graph shows the number of students who like different sports. The bar for Cricket is the tallest and reaches 25. How many students like Cricket?
Show Answer+
Answer: 25
Hint: In a bar graph, the height of each bar represents the value it shows.
Solution:
In a bar graph, the height (or length) of a bar represents its value.
The bar for Cricket reaches 25 on the scale, so 25 students like Cricket.
8What is the mean of the first five natural numbers?
Show Answer+
Answer: 3
Hint: The first five natural numbers are 1, 2, 3, 4, 5. Find their average.
Solution:
First five natural numbers: 1, 2, 3, 4, 5.
Sum: — 1 + 2 + 3 + 4 + 5 = 15
Mean: — 15 / 5 = 3
9In a frequency table, if the tally for 'Mango' is |||| || , how many students chose Mango?
Show Answer+
Answer: 7
Hint: One bundle of tally marks is 5, then count the remaining individual marks.
Solution:
One complete tally bundle = 5.
Remaining individual marks = 2.
Total: — 5 + 2 = 7
10Which of the following is NOT a way to represent data?
Show Answer+
Answer: Equation
Hint: Think about which option is used in algebra rather than in data handling.
Solution:
Bar graphs, pictographs, and frequency tables are all standard methods to represent data.
An equation is a mathematical statement used in algebra, not a data representation tool.
