Variation compared with di mean
Compare di sample standard deviation with di mean wey positive.
Your numbers
Di coefficient of variation
E no suitable for scales wey get arbitrary zero, like Celsius temperatures, or means wey near zero.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use CV = 100s/μ. s na sample standard deviation and μ na di positive arithmetic mean of di nonnegative observations wey you enter. Di coefficient of variation dey show as percentage.
Compare di sample standard deviation with di mean wey positive.
Example wey show the calculation
- Observations wey no dey negative
- 10, 20, 30
- Di coefficient of variation
- 50 %
- Di sample standard deviation
- 10
- Mean
- 20
Where e fit work and limits
E no suitable for scales wey get arbitrary zero, like Celsius temperatures, or means wey near zero.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
