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