Control Chart Calculator: run control chart calculations online. Formula, assumptions, and interpretation guide.
Simple moving average (SMA): SMAₜ = (xₜ + xₜ₋₁ + ... + xₜ₋ₙ₊₁) / n
Exponential smoothing: Sₜ = α × xₜ + (1−α) × Sₜ₋₁, where α is the smoothing factor (0 < α < 1)
Period growth rate: g = (xₜ / xₜ₋₁) − 1
Compound annual growth rate (CAGR): CAGR = (xₙ / x₀)^(1/n) − 1
