Worked Example
Reasoning practice 4
For Class 11 Economics, explain or solve a mean deviation question from the chapter "Measures of Dispersion". Focus on reasoning practice and show the working clearly.
Step-by-step solution path
- Read the topic idea: Mean deviation.
- Recall the core explanation from the chapter: Economics syllabus chapter for Class 11.
- Use the related formula "CV = (SD/Mean) × 100" 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 Mean deviation. A strong solution should identify the correct data, apply CV = (SD/Mean) × 100, and explain each transition instead of jumping directly to the answer.
