🎯 Exam Tip: Pay close attention to the scale given for each symbol when filling in blanks related to pictographs to ensure accurate representation.

Question 2. Draw a pictograph for the given data.

Answer: To draw a pictograph, we use a simple picture (like 💻) to represent a certain number of computers. For this data, we use the scale where 1 💻 = 100 computers.
    June: 300 computers will be shown by 3 💻
    July: 450 computers will be shown by 4 💻 and half of 💻
    August: 600 computers will be shown by 6 💻
    September: 550 computers will be shown by 5 💻 and half of 💻
This visual chart clearly shows the sales for each month.
In simple words: We draw pictures of computers. Each full picture means 100 computers. For 50 computers, we draw half a picture.

🎯 Exam Tip: Always state the key or scale clearly at the bottom of your pictograph so everyone knows what each picture represents and can understand the data.

Question 3. The following table shows the number of tourists who visited the places in the month of May. Draw a pictograph

Answer: To draw this pictograph, we will use a symbol like 🚶 to represent 10,000 visitors. This is our chosen scale.
    Mahabalipuram: 20,000 tourists = 2 🚶
    Vedanthangal: 15,000 tourists = 1 🚶 and half of 🚶
    Hogenakkal: 40,000 tourists = 4 🚶
    Ooty: 35,000 tourists = 3 🚶 and half of 🚶
This pictograph helps to quickly compare the number of visitors at each place.
In simple words: We draw pictures of people. Each full picture means 10,000 tourists. For 5,000 tourists, we draw half a picture.

🎯 Exam Tip: When dealing with large numbers, pick a scale for your pictograph that simplifies the representation without losing accuracy. For example, a single picture representing 10,000 or 100,000 visitors.

Question 4. Answer the following questions.

The pictograph shows the number of students playing different games in a school. Each little person symbol represents 10 students.

Answer:
(i) Kabaddi is the most popular game among students as it has the highest number of players (110 students).
(ii) The number of students playing Kabaddi is \( 11 \times 10 = 110 \) students.
(iii) Kho-Kho and Hockey are played by an equal number of students, with 90 students each.
(iv) The number of students playing Kho-Kho is 90 and Hockey is 90. So, the difference between them is \( 90 - 90 = 0 \). There is no difference.
(v) Basketball is the least popular game among students, having the fewest players with only 70 students.
In simple words:
(i) Kabaddi is most liked by students.
(ii) 110 students play Kabaddi.
(iii) Kho-Kho and Hockey have the same number of players.
(iv) There is no difference in the number of players between Kho-Kho and Hockey.
(v) Basketball is liked by the fewest students.

🎯 Exam Tip: When answering questions based on a pictograph, always refer to the key or scale to accurately calculate the quantities represented and ensure your comparisons are correct.
