About Coefficient of Variation Calculator
The Coefficient of Variation Calculator measures the relative variability of a dataset by calculating the ratio of the sample standard deviation to the mean, expressed as a percentage.
How to Use
- Enter a list of numbers, separated by commas or spaces (e.g., 1, 2, 3 or 1 2 3).
- Click “Calculate” to compute the mean, sample standard deviation, and coefficient of variation. The page will scroll to the result.
- Click “Clear” to reset the input and results.
- Click “Share” to copy the calculator’s URL to your clipboard.
- Click “Embed” to copy an iframe code for embedding on another website.
- The results and calculation steps will be displayed.
Formula
CV = (s / μ) × 100
Where:
- CV = coefficient of variation (%)
- s = sample standard deviation
- μ = mean of the dataset
Steps include:
1. Mean (μ) = Σx / n
2. Variance (s²) = Σ(x – μ)² / (n – 1)
3. Standard Deviation (s) = sqrt(s²)
Where:
- Σx = sum of all numbers
- n = number of data points
- x = each data point
Important Notes
- Enter at least two numbers to calculate the coefficient of variation.
- Numbers can be integers or decimals, separated by commas or spaces.
- The mean must be non-zero to avoid division by zero.
- The keypad’s Clear button clears the input field.
- “Share” and “Embed” buttons require a browser that supports the Clipboard API.
