Table 9 Metrics formulas
From: Addressing big data variety using an automated approach for data characterization
Metric | Formula |
|---|---|
Mean (μ) | \(\mu = \frac{{\sum x_{i} }}{n}\) |
Standard Deviation (σ) | \(\sigma = \sqrt {\frac{{\sum \left( {x_{i} - \mu } \right)^{2} }}{n}}\) |
Coefficient of Variation (Cv) | \(C_{v} = \frac{\sigma }{\mu }\) |
