For Class 11 Economics, explain or solve a coefficient of variation 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: Coefficient of variation.
Recall the core explanation from the chapter: Economics syllabus chapter for Class 11.
Use the related formula "SD = โ(ฮฃfdยฒ/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 Coefficient of variation. A strong solution should identify the correct data, apply SD = โ(ฮฃfdยฒ/N), and explain each transition instead of jumping directly to the answer.
