Data Handling

Note: The picture (img_1.png) cannot be seen directly. The solution below uses a typical/standard set of values used in NCERT Class 2 Data Handling for this activity. Adjust the numbers if your picture shows different counts.

Assumed data from the picture:
- Red = 6 children
- Green = 4 children
- Blue = 8 children
- Yellow = 5 children

Completed Table:

| Colours | Red | Green | Blue | Yellow |
|---|---|---|---|---|
| Number of Children | 6 | 4 | 8 | 5 |

Step-by-step answers:

A. Compare all numbers: Red = 6, Green = 4, Blue = 8, Yellow = 5.
The largest number is 8 (Blue).
$$\text{Most liked colour} = \textbf{Blue}$$

B. The smallest number is 4 (Green).
$$\text{Least liked colour} = \textbf{Green}$$

C. Yellow = 5, Green = 4. Since 5 > 4:
Yellow colour is liked more than Green.

D. Red = 6, Green = 4. Since 6 > 4:
Red colour is liked more than green.

E. Green = 4, Yellow = 5. Since 4 < 5:
Green colour is liked less than Yellow.

Assumed data from the picture:
- Apple = 4 children
- Banana = 6 children
- Guava = 3 children
- Orange = 5 children
- Kiwi = 2 children

Completed Table:

| Fruits | Apple | Banana | Guava | Orange | Kiwi |
|---|---|---|---|---|---|
| Number of Children | 4 | 6 | 3 | 5 | 2 |

Step-by-step answers:

A. Total children $= 4 + 6 + 3 + 5 + 2 = \mathbf{20}$

B. Number of children who like apples $= \mathbf{4}$

C. Largest value = 6 (Banana).
Most liked fruit = Banana

D. Smallest value = 2 (Kiwi).
Least liked fruit = Kiwi

E. Guava = 3, Apple = 4. Since 3 < 4:
Number of children who like guava is less than the number of children who like apple.

F. Apple = 4, Banana = 6. Since 4 < 6:
The number of children who like apple is less than the number of children who like banana.

G. Orange = 5, Kiwi = 2. Since 5 > 2:
The number of children who like orange is more than the number of children who like kiwi.

Assumed data from the picture:
- Bus = 8 students (given in table)
- Autorickshaw = 5 students
- Bike = 3 students
- Bicycle = 6 students

Completed Table:

| Mode of coming to school | Number of students |
|---|---|
| Bus | 8 |
| Autorickshaw | 5 |
| Bike | 3 |
| Bicycle | 6 |

Pictograph (😊 = 1 student):

| Mode | Faces |
|---|---|
| Bus | 😊😊😊😊😊😊😊😊 |
| Autorickshaw | 😊😊😊😊😊 |
| Bike | 😊😊😊 |
| Bicycle | 😊😊😊😊😊😊 |

Step-by-step answers:

A. Largest value = 8 (Bus).
Most number of students come to school by Bus.

B. Smallest value = 3 (Bike).
Least number of students come to school by Bike.

C. Bus = 8, Autorickshaw = 5. Since 8 > 5:
The number of students who come to school using bus is more than the number of students who come using autorickshaw.

D. Bike = 3, Bicycle = 6. Since 3 < 6:
The number of students who come to school using bike is less than the number of students who come using bicycle.

E. Bike is less than Bus.
(Any pair where one mode has fewer students than another is acceptable, e.g., Bike < Bicycle, Autorickshaw < Bus.)

F. Bus is more than Bicycle.
(Any pair where one mode has more students than another is acceptable, e.g., Bus > Autorickshaw, Bicycle > Bike.)

Assumed data from the picture:
- Cricket = 7 students
- Football = 4 students
- Pithu = 6 students
- Kabaddi = 3 students

Completed Table:

| Games | Number of Students |
|---|---|
| Cricket | 7 |
| Football | 4 |
| Pithu | 6 |
| Kabaddi | 3 |

Pictograph (😊 = 1 student):

| Game | Faces |
|---|---|
| Cricket | 😊😊😊😊😊😊😊 |
| Football | 😊😊😊😊 |
| Pithu | 😊😊😊😊😊😊 |
| Kabaddi | 😊😊😊 |

Step-by-step answers:

A. Largest value = 7 (Cricket).
The most liked game is Cricket.

B. Smallest value = 3 (Kabaddi).
The least liked game is Kabaddi.

C. Pithu = 6, Football = 4. Since 6 &gt; 4:
Pithu is liked more than Football.

D. Cricket = 7, Football = 4. Since 7 &gt; 4:
Cricket is liked more than football.

Note: This is a class activity. Students must collect data from their own classmates. The answers will vary for each class. Below is a sample solution based on assumed data.

Sample Assumed Data (students fill their own):

| Vegetable | Number of Students |
|---|---|
| Potato | 10 |
| Tomato | 6 |
| Carrot | 4 |
| Spinach | 3 |
| Peas | 7 |

Step-by-step answers (based on sample data):

i. Largest value = 10 (Potato).
Most liked vegetable is Potato.

ii. Smallest value = 3 (Spinach).
Least liked vegetable is Spinach.

iii. Potato (10) &gt; Peas (7):
Potato is liked more than Peas.
(Students may write any valid pair from their own data.)

iv. Spinach (3) &lt; Carrot (4):
Spinach is liked less than Carrot.
(Students may write any valid pair from their own data.)

Note: This is a class/community activity. Students must collect data from their own friends. The answers will vary for each class. Below is a sample solution based on assumed data.

Sample Assumed Data (students fill their own):

| Number of people living together | How many families |
|---|---|
| 1 People | 1 |
| 2 People | 2 |
| 3 People | 4 |
| 4 People | 8 |
| 5 People | 5 |
| 6 People | 3 |
| 7 People | 1 |

Step-by-step answers (based on sample data):

i. The category with the highest frequency = 8 families (4 people).
Most families have 4 people in their homes.

ii. The smallest group size recorded = 1 person.
The least number of people living in a home is 1.

iii. From the table, families having 4 people = 8.

iv. Families having more than 4 people $=$ families with 5 + 6 + 7 people $= 5 + 3 + 1 = \mathbf{9}$.

Note: This is a project/field activity. Students must visit nearby families and collect real data. The answers will vary for each student. Below is a sample solution based on assumed data to show how to fill and interpret the table.

Sample Assumed Data (students fill their own after visiting families):

| Families living with | Both grandparents | Only female grandparents | Only male grandparents | No grandparents |
|---|---|---|---|---|
| Number of Families | 5 | 3 | 2 | 4 |

Step-by-step answers (based on sample data):

Total families visited:
$$5 + 3 + 2 + 4 = \mathbf{14} \text{ families}$$

Number of families living with both grandparents $= \mathbf{5}$

How many families live with one grandparent?
(Only female grandparents + Only male grandparents)
$$= 3 + 2 = \mathbf{5} \text{ families}$$

How many families live without grandparents? $= \mathbf{4}$

*Students should discuss the questions they will ask before visiting the families, as instructed in the textbook.*
