PRESENTATION OF PICTOGRAPH

**PRESENTATION OF PICTOGRAPH -**

**Pictographs are a visual representation of data using symbols or pictures to convey information. They are a form of data visualization that can make complex information more accessible and understandable. Here's a breakdown of how you might structure your presentation:**

**Slide 1: Introduction :- **

**Title: "Understanding Pictographs: Visualizing Data Through Symbols"****Briefly explain the purpose of the presentation: To explore the concept of pictographs, understand their significance, and learn how to create and interpret them.**

**Slide 2: What are Pictographs? :-**

**Definition: Pictographs are a type of data visualization that uses simple icons or symbols to represent quantities or categories.****Highlight their historical significance: Pictographs have been used since ancient times to communicate information before the advent of written language.**

**Slide 3: Advantages of Pictographs :-**

**Clarity and Accessibility: Pictographs simplify complex data and make it easier for people to understand.****Universal Language: Pictographs can often be understood across cultures and languages.****Engaging: Visual elements capture attention and encourage viewer engagement.**

**Slide 4: Elements of a Pictograph :-**

**Symbol: The visual representation used to convey information.****Key or Legend: An explanation of what each symbol represents.****Data Set: The actual data that the pictograph is based on.**

**Slide 5: Creating a Pictograph :-**

**Step-by-step guide:Choose a topic and data to visualize.Select symbols that are relevant and easy to understand.Create a key or legend that associates symbols with data values.Arrange the symbols according to the data.Title and label your pictograph appropriately.**

**Slide 6: Interpreting a Pictograph :-**

**Discuss how to read a pictograph:Look at the symbols and their corresponding values in the key.Count the number of symbols to determine quantities.Analyze trends and patterns, such as which symbols appear most frequently.**

**Slide 7: Examples of Pictographs :-**

**Show a few examples of pictographs from different contexts (e.g., education, health, sports) to illustrate their versatility and application.**

**Slide 8: Dos and Don'ts :-**

**Dos: Keep symbols consistent, use appropriate scaling, ensure clarity, and provide a clear key.****Don'ts: Overcomplicate symbols, use misleading scales, omit legends, or distort the data.**

**Slide 9: Real-World Applications :-**

**Explain how pictographs are used in various fields, such as:Education: Teaching children basic math concepts.Marketing: Visualizing survey results for product preferences.Environment: Showing wildlife population trends.**

**Slide 10: Conclusion :-**

**Summarize the key points discussed in the presentation.****Emphasize the importance of pictographs in making data more accessible and engaging.****Encourage the audience to explore using pictographs for their data visualization needs.**

**Slide 11: Q&A :-**

**Allocate time for questions from the audience to address any queries they might have about pictographs.**

**Remember to use visual elements effectively in your presentation and keep the content concise and engaging. Good luck with your presentation on pictographs!**

**Example.1) The following
pictograph shows the number of cars sold by four dealers A,B,C and D in a city.
Scale: 1 car image = 50 cars**

**Using the pictograph, drawn above, answer the following question :**

**(i) How many more cars has dealer A sold as compared to dealer D ?**

**(ii) What is the total number of cars sold by all the dealers ?**

**Using the pictograph, shown above, answer the following question: How many more cars has dealer A sold as compared to dealer D?**

**Ans.) A sold cars = (50 X 6) = 300 cars [1 car pic = 50 cars]**

** D sold cars = (50 X 4) = 200 cars [1 car pic = 50 cars]**

**So, dealer A sold as compared to dealer D = (A - D) **

** = (300 - 200)**

** = 100 cars .....(i) (Ans.)**

**Dealer A sold = (50 X 6) = 300 cars [1 car pic = 50 cars]**

**Dealer B sold = (50 X 5) = 250 cars [1 car pic = 50 cars]**

**Dealer C sold = (50 X 8) = 400 cars [1 car pic = 50 cars]**

**Dealer D sold = (50 X 4) = 200 cars [1 car pic = 50 cars]**

**Car sold by all dealers = A + B + C + D**

** = 300 + 250 + 400 + 200**

** = 1150 cars .................(ii) (Ans.)**

**Example.2) The pictograph shows different subject books which are kept in a library. Observe the graph and answer the following questions.**

**How many English books are there in the library?**

**Ans.) English books are there in the said library -**

** 8 pic of books X 100 books [1 pic of book = 100 books] **

**= 800 books (Ans.)**

**Example.3) The number of girl students
in each class of co-ed. Middle school is depicted by the following pictograph:**

**Observe the above pictograph and answer the following questions: How many girls are there in VII class?**

**What is the total number of girls in co-ed. Middle school ?**

**Ans.) The number of girls are there in VII class => (3 X 4) **

** = 12 girls**

**Number of girls in Class I = (6 X 4) = 24 girls**

**Number of girls in Class II = (4 X 4) + (4 X 1/2) = (16 + 2) = 18 girls**

**Number of girls in Class III = (5 X 4) = 20 girls**

**Number of girls in Class IV = (3 X 4) + (4 X 1/2) = (12 + 2) = 14 girls**

**Number of girls in Class V = (2 X 4) + (4 X 1/2) = (8 + 2) = 10 girls**

**Number of girls in Class VI = (4 X 4) = 16 girls**

**Number of girls in Class VII = (3 X 4) = 12 girls**

**Number of girls in Class VIII = (1 X 4) + (4 X 1/2) = (4 + 2) = 6 girls**

**Total girls of that school from Class I to Class VIII -**

**(24 + 18 + 20 + 14 + 10 + 16 + 12 + 6) = 120 girl students (Ans.)**
