What is the formula for finding coefficient of variation, given \(\sigma=\) standard deviation and \(\bar{x}=\) mean \(\neq 0\) ?
\(\frac{\bar{x}}{\sigma} \times 100\)
\(\frac{\bar{x}}{\sigma}\)
\(\frac{\sigma}{\bar{x}}\)
\(\frac{\sigma}{\bar{x}} \times 100\)
Solution
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.
