Worked Example
Formula warm-up 3
For Class 11 Economics, explain or solve a range question from the chapter "Measures of Dispersion". Focus on formula warm-up and show the working clearly.
Step-by-step solution path
- Read the topic idea: Range.
- Recall the core explanation from the chapter: Economics syllabus chapter for Class 11.
- Use the related formula "SD = √(Σfd²/N)" as the main tool while solving.
- Write the reasoning in simple school-level language before the final answer.
Final learning answer
This example is centred on Range. A strong solution should identify the correct data, apply SD = √(Σfd²/N), and explain each transition instead of jumping directly to the answer.
