Calculate coefficient of variation, given the following data-set:

Explanation

`barX=A+(sumfdx)/(N)xxC`
`=35+(46)/(50)xx10=44.2`
`sigma=sqrt((sumfdx'^(2))/(N)-((sumfdx')/(N))^(2))xxC`
`=sqrt((204)/(50)-((46)/(50))^(2))xx10`
`=sqrt(4.08-(0.92)^(2))xx10`
`=sqrt(4.08-0.8464)xx10`
`=sqrt(3.2363)xx10`
`=1.798xx10=17.98`
`CV=(sigma)/(barX)xx100`
`=(17.98)/(44.2)xx100=40.68`
Coefficient of Variation=40.68.
