Class 6 Maths Data Handling and Presentation MCQ
Question 1.
The marks (out of 10) obtained by 28 students in a Mathematics test are listed as below:
8, 1, 2, 6, 5, 5, 5, 0, 1, 9, 7, 8, 0, 5, 8, 3, 0, 8, 10, 10, 3, 4, 8, 7, 8, 9, 2, 0
The number of students who obtained marks more than or equal to 5 is:
(a) 3
(b) 15
(c) 16
(d) 17
Solution:
(d) 17
The given marks can be arranged in ascending order as follows:
0, 0, 0, 0, 1,1,2, 2, 3, 3, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10
Hence, the number of students who obtained marks more than or equal to 5 is 17.
Question 2.
The table below shows the marks obtained by 5 students in Science exam.
| Name of Student | Attendance Marks | Assignment Marks | Theory (Marks) | Total marks |
| Abhijeet | 5 | 10 | 45 | 60 |
| Rajeev | 4 | 8 | 58 | 70 |
| Simran | 5 | 6 | 38 | 49 |
| Karuna | 5 | 9 | 57 | 71 |
| Jatin | 4 | 10 | 65 | 79 |
Which student scored the highest marks in theory?
(a) Karima
(b) Jatin
(c) Abhijeet
(d) Simran
Solution:
(b) Jatin
From the table, we can see that the theory
column contains the highest marks of 65, which corresponds to Jatin. Hence, Jatin scored the highest marks in theory.
Question 3.
A dice is rolled 20 times. Following tally table shows which number comes up how many times.
Which of the number appeared maximum number of times?
(a) 1
(b) 2
(c) 3
(d) 6
Solution:
(a) 1
1 appears 7 times, which is maximum.
Question 4.
The following bar graph shows number of toys produced by a company during certain week:
The minimum number of toys produced on:
(a) Tuesday
(b) Monday
(c) Friday
(d) Saturday
Solution:
(d) Saturday
The bar graph shows that the minimum number of toys were produced on Saturday, with a total of 40.
Question 5.
The pictograph shows the number of bouquets sold by a flower shop in the past 4 days.
What is the difference between the maximum number of bouquets sold and the least number of bouquets sold?
(a) 5
(b) 21
(c) 15
(d) 33
Solution:
(b) 21
Maximum number of bouquets sold on thursday = 10 × 3 = 30
Least number of bouquets sold on Wednesday = 3 × 3 = 9
The difference between the maximum and least number of bouquets sold = 30 – 9 = 21
Question 6.
The following bar graph shows the number of sections in a class from class VI to class X:
The pair of classes in which the number of sections is same, is:
(a) VIII and X
(b) VIII and IX
(c) VII and IX
(d) IX and X
Solution:
(b) VIII and IX
The given bar graph shows that the number of sections is same in classes VIII and IX, equal to 4.
Question 7.
From the bar graph given in previous question, the total number of sections from class VI to class X, is:
(a) 19
(b) 20
(c) 22
(d) 25
Solution:
(c) 22
From the given bar graph,
Number of sections in class VI = 6
Number of sections in class VII = 5
Number of sections in class VIII = 4
Number of sections in class IX = 4
Number of sections in class X = 3
So, total number of sections from classes VI to X = 6 + 5 + 4 + 4 + 3 = 22
Question 8.
What are the advantages of using a bar graph over a pictograph?
(i) Bar graphs are more accurate for large values.
(ii) Bar graphs can be made fancy with pictures.
(iii) It is easier to compare different categories with bar graphs.
(iv) It can be more challenging to prepare a pictograph than a bar graph when the frequencies are not exact multiples of the scale
Choose the correct option from the following:
(a) Only (i) and (iv)
(b) Only (i) and (ii)
(c) (i), (ii) and (iii)
(d) (i), (iii) and (iv)
Solution:
(d) (i), (iii) and (iv)
Pictographs are a nice visual and suggestive way to represent data. They represent data through pictures of objects. It can be more challenging to prepare a pictograph when the amount of data is large or when the frequencies are not exact multiples of the scale or key. It is also easier to compare different categories of data with bar graphs.
Question 9.
A class has these shoe sizes (already in order):
3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 6, 6, 6, 6, 7
(i) The shoe size range is 4.
(ii) There are 10 students with size 4.
(iii) Shoe size 4 is worn by more students than size 3.
(iv) Size 6 is the most common.
Choose the correct option from the following:
(a) Only (i) and (iv)
(b) Only (i) and (iii)
(c) (i), (ii) and (iii)
(d) (i), (iii) and (iv)
Solution:
(b) Only (i) and (iii)
We have, size range = largest size – smallest size
= 7 – 3 = 4.
From the given list of shoe size, there are 8 students who wore shoes of size 4 while, and there are 3 students who wore shoes of size 3. Therefore, shoe size 4 is worn by more students than size 3.
Also, there are 10 students who wore shoes of size 5, while there are only 4 students who wore shoes of size 6. So, size 5 is the most common.
Question 10.
In which of the following situations data needs to be collected?
(i) Finding out the favourite fruit of 10 people.
(ii) Finding out the capital city of a state.
(iii) Counting the number of pets that the students own.
(iv) Finding out the total runs scored by Sachin Tendulkar in test cricket. ,
Choose the correct option from the following:
(a) Only (i) and (iii)
(b) Only (ii) and (iv)
(c) (i), (ii) and (iii)
(d) (i), (iii) and (iv)
Solution:
(a) Only (i) and (iii)
We would need to ask each of the 10 people about their favourite fruit. So, this is an example of data collection.
The capital city of a particular state is a known fact, so there is no need to collect data.
We would need to ask each student about the number of pets they have, so this is an example of data collection.
Again, the total runs scored by Sachin Tendulkar in test cricket is a known fact, so there is no need to collect data.
Data Handling and Presentation Class 6 Assertion and Reason Questions
The following questions are Assertion and Reason based questions. Two statements are given, one labelled as Assertion (A) and the other is labelled as Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
Question 1.
(A): In a bar graph, all bars must be of equal width.
(R): Equal width ensures that the comparison is based only on the height of the bars.
Solution:
(a) Both A and R are true and R is the correct explanation of A.
Uniform width of bars is essential to not confuse width with quantity. Only height (or length) of the bar should represent value (frequency). Having equal widths supports accurate comparison.
Thus, both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
Question 2.
(A): Bar graph with vertical bars is better to represent height of mountains.
(R): Vertical bars help us visually interpret increasing values as ‘growing upward’, like heights.
Solution:
(a) Both A and R are true and R is the correct explanation of A.
Heights naturally grow upwards. The vertical bars give an intuitive and realistic feel when comparing heights (like of mountains or buildings). The reason explains the assertion.
Thus, both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).
