Coefficient of Variation Calculator

CV batata hai ke data apne average ke around kitna bikhra hua hai — do datasets compare karne ke liye best metric.

Formula

CV = (standard deviation / mean) x 100

Sample CV me sample standard deviation (n-1) use hota hai, population CV me population SD (n) — calculator dono dikhata hai.

Kab use karein?

• Do groups ka spread compare karna ho jab unke units ya averages alag hon.
• Investment me risk-per-return dekhna ho (CV kam = zyada consistent).
• Lab / quality control me measurement variability check karni ho.

CV sirf tab meaningful hai jab mean positive aur zero ke qareeb na ho.
