What is the formula for finding coefficient of variation, given \(\sigma=\) standard deviation and \(\bar{x}=\) mean \(\neq 0\) ?
- A \(\frac{\bar{x}}{\sigma} \times 100\)
- B \(\frac{\bar{x}}{\sigma}\)
- C \(\frac{\sigma}{\bar{x}}\)
- D \(\frac{\sigma}{\bar{x}} \times 100\)
Answer & Solution
Correct Answer
(D) \(\frac{\sigma}{\bar{x}} \times 100\)
Step-by-step Solution
Detailed explanation
Coefficient of variation, having standard deviation \(\sigma\) and mean \(\bar{x} \neq 0\), is \(\frac{\sigma}{\bar{x}} \times 100\) Hence, option (d) is correct.
