How to Evaluate Coefficient of Variation?

Coefficient of Variation evaluator uses Variation Coefficient = Standard Deviation*100/Arithmetic Mean to evaluate the Variation Coefficient, The Coefficient of Variation formula is defined as variation between two objects or between two considered groups. If V of group A is less compared to B, A is considered a less variable group or a more consistent and reliable group. Variation Coefficient is denoted by V symbol.
