FAQs on RD Sharma Class 6 Maths Solutions Chapter 22 - Data Handling II (Pictographs)
1. How does RD Sharma Class 6 Maths Chapter 22 explain the concept of a pictograph for solving problems?
RD Sharma Chapter 22 explains a pictograph as a method of representing numerical data using pictures or symbols. To solve the exercises in this chapter, it is essential to understand that each symbol corresponds to a specific quantity defined by a 'key'. This visual approach simplifies the comparison and interpretation of data, aligning with the Class 6 CBSE syllabus for Data Handling.
2. What is the correct method for drawing a pictograph as required in RD Sharma Chapter 22 exercises?
To accurately solve questions that require drawing a pictograph, follow these steps as per the methodology in RD Sharma:
First, gather and organise the given data in a table.
Select a simple, relevant picture or symbol to represent the items.
Establish a 'key' or 'scale' that defines the value of one symbol (e.g., 1 symbol = 10 books). This is the most crucial step.
Draw the required number of symbols for each category based on your key.
Provide a clear title for the pictograph to explain what data it represents.
3. How is the 'key' used to solve interpretation problems in RD Sharma Class 6 Maths Chapter 22?
In the RD Sharma solutions for this chapter, the 'key' is fundamental for accurate interpretation. It tells you the numerical value of a single symbol. To solve a problem, you must first count the number of symbols for a category and then multiply that count by the value given in the key. Forgetting to use the key is a common source of errors in these problems.
4. What is a common mistake students should avoid when solving pictograph problems from RD Sharma Chapter 22?
A common mistake is assuming that one symbol equals one unit without checking the pictograph's key. For example, if a symbol of a flower represents 20 flowers and there are 5 symbols, the total is 100, not 5. To solve problems correctly, you must always multiply the number of symbols by the key's value before performing any calculation or comparison.
5. How do you solve comparison questions in RD Sharma Chapter 22, like finding 'how many more' or 'how many less'?
To solve comparison problems, follow this precise method:
First, use the key to find the total value for each category you are comparing.
Then, subtract the smaller total value from the larger one.
The result of this subtraction is the correct answer. For example, if category A has 5 symbols (key=10) and category B has 3 symbols (key=10), the difference is (5 × 10) - (3 × 10) = 20.
6. Why is choosing an appropriate 'key' the most critical step when representing large data sets in this chapter?
Choosing an appropriate 'key' is critical for large data sets because it makes the information compact, readable, and manageable. If you had to represent 1,000 cars, drawing 1,000 symbols would be impractical. By setting a key like '1 symbol = 200 cars', you only need to draw 5 symbols. This makes the pictograph easier to create and interpret, which is a key skill tested in this chapter.
7. In the context of Data Handling, when is using a pictograph a better method than using a bar graph?
A pictograph is a better choice when the primary goal is to present data in a visually engaging and easily understandable manner, especially for a non-technical audience. It works best when data can be represented by a simple, intuitive symbol. While a bar graph provides more precision for detailed numerical analysis, a pictograph offers a quicker, at-a-glance comparison of quantities, which is often the focus of introductory data representation problems.
