Question

For a random variable \(X\) with mean \(\mu\) and variance \(\sigma^2\), the coefficient of variation is:

• A. \(\frac{\mu}{\sigma} \times 100\)
• B. \(\frac{\sigma}{\mu} \times 100\)
• C. \(\frac{\sigma^2}{\mu} \times 100\)
• D. \(\frac{\mu}{\sigma^2} \times 100\)

Hint:

Coefficient of variation = \(\frac{\text{Standard Deviation}}{\text{Mean}} \times 100\).
It is used to compare the variability of two or more datasets.
