Calculation Formulas
Simple Average
The simple average (arithmetic mean) is calculated by summing all values and dividing by the number of values:
- Average = (x₁ + x₂ + ... + xₙ) / n
- Where x₁, x₂, ..., xₙ are the percentage values and n is the count
Weighted Average
The weighted average accounts for the importance (weight) of each value:
- Weighted Average = (w₁×x₁ + w₂×x₂ + ... + wₙ×xₙ) / (w₁ + w₂ + ... + wₙ)
- Where w₁, w₂, ..., wₙ are the weights and x₁, x₂, ..., xₙ are the percentage values
Standard Deviation
Standard deviation measures the amount of variation or dispersion in a set of values:
- σ = √[(Σ(xᵢ - μ)²) / N]
- Where σ is standard deviation, xᵢ represents each value, μ is the mean, and N is the count
