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

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.
