Property Value

Applies two rules:

• PointBeyondControlLimits — one point beyond ±3σ (window length 1).
• ConsecutivePointsOnSameSide(Int32) with run length 9 — nine consecutive points on the same side of the center line (window length 9).

Zone rules (beyond ±1σ or ±2σ) are excluded because attribute chart statistics follow binomial or Poisson distributions rather than normal distributions, making the zone-based probability assumptions invalid and likely to produce excessive false alarms.
