Mixer Uniformity CV Analyzer
Paste sample assay results to calculate mean, standard deviation, and coefficient of variation for mixer performance checks.
How it calculates
- Mean = sum of samples ÷ n.
- Sample standard deviation uses n − 1 (Bessel’s correction).
- CV% = (standard deviation ÷ |mean|) × 100.
