Coefficient of variation

—

Not suitable for arbitrary zero scales such as Celsius temperatures or means close to zero.

Formula

Use CV = 100s/μ. s is sample standard deviation and μ is the positive arithmetic mean of the entered nonnegative observations. The coefficient of variation is displayed as a percentage.

Compare sample standard deviation with a positive mean.

Worked example

Nonnegative observations
10, 20, 30
Coefficient of variation
50 %
Sample standard deviation

Mean
20

Scope and limitations

Not suitable for arbitrary zero scales such as Celsius temperatures or means close to zero.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
