Calculation of Standard deviation and Co-efficient of variance.[br]This app calculates Standard deviation and coeff of variance. It is enough if you give first term of the distribution, width of class interval at input box provided. Then you have to give values at input boxes for frequencies. The program tabulates finds the value of SD.
