Question

Standard Deviation of a set of data is more than its mean. The percentage coefficient of variance is.

• A. more than 100
• B. less than 100
• C. equal to 100

Answer 1

The correct option is A more than 100

$\mathrm{Percentage}\mathrm{CV}=\frac{\mathrm{SD}}{\mathrm{Mean}}\times 100=\frac{\mathrm{Mean}+a}{\mathrm{Mean}}\times 100\mathrm{Hence}\mathrm{it}\mathrm{is}\mathrm{more}\mathrm{than}100.$
