Average & Dispersion: Replicate Statistics

Calculate the arithmetic mean, standard deviation, and coefficient of variation for a set of experimental data.

Try this tool

x̄ = —(n = 0)

Std. Dev. (s): ± —

CV: —

*Empty columns are discarded

When to use this tool

Analysis of experimental replicates, measurement quality control, evaluation of analytical method precision.

How it works

Enter your values and get: arithmetic mean (x̄), sample standard deviation (s), and coefficient of variation (CV%). CV indicates relative dispersion: values < 5% indicate good precision.
