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
