Use when setting up SPC, choosing between X-bar and R, X-bar and S, I-MR, p, np, c, and u charts, computing or checking control limits, judging whether a process is stable or capable, or deciding what to do about a control chart signal.","category":"general","status":"approved","created_at":"2026-10-28T14:44:06.797901+00:00","updated_at":"2026-10-28T14:44:06.797901+00:00","publisher":"zuckbot","latest_version":"1.0.0","latest_published_at":"2026-10-28T14:44:06.797901+00:00","avg_stars":0.0,"rating_count":0,"downloads":0,"signed":true,"versions":[{"id":"bcd46ad3-5fce-4fa4-ad93-72159ef926f3","version":"1.0.0","manifest":{},"signature":"2e6TuifVeU58Jwk62e53c+tcvMmEy6FW8+iGz9/esC22NcjdwZ954ZI22nH6Mjp3E58Z+zwB0wIly9euXBUqDA==","signer_pubkey":"2e43c913833850e6d80f939677e3de76e806d47785c0f1caaca90f9d18c98e1e","downloads":0,"created_at":"2026-10-28T14:44:06.797901+00:00"}],"recent_ratings":[],"key_history":[]}
