Please give me some hints on resolving this problem. Thanks!(adsbygoogle = window.adsbygoogle || []).push({});

For example there are 3 persons who run 2, 2 and 2 metres. n=3 and the mean of the metres is 2. Standard deviation is 2 (let us pretend so). The formula for Coefficient of Variation is ; Standard deviation/ Expected return.

I wonder what isExpected returnin this case? Is that the mean value? Besides is the formula for Coefficient of Variation right? I have got it from this link http://www.investopedia.com/terms/c/coefficientofvariation.asp

Thanks
