Assumptions and interpretation
- Graphs are not evidence of causation. Check axis units and measurement provenance.
- Error bars represent the user-entered Y standard uncertainties; they are not confidence intervals.
Educational calculations are not substitutes for professional engineering design approvals, certified laboratory assays, clinical diagnostics, or peer-reviewed scientific publications. Always inspect units, verify physical domains, and evaluate boundary conditions.
