PHY.9:8 - Common Anti-Patterns and How to Avoid Them

Anti-pattern	What fails	Repair
The quantity appears, so it is measured	Mass cancels from ideal falling acceleration.	Derive the complete response and choose a coupling that retains the wanted dependence.
Responsive interaction, insensitive readout	A relative phase changes while a population measurement stays constant.	Choose preparation and readout together with the interaction.
Common offset by notation	Two preparations use one symbol for physically different influences.	Establish the shared condition or retain separate contributions.
More readings resolve every ambiguity	Repetition improves a statistic without separating compatible target values.	Change the interaction or use the sufficient compatible range.
Correction without the coupled arrangement	Probe loading is removed by a formula from another physical setup.	Derive the effect for the actual target and probe conditions.
Maximum local slope means best measurement	A periodic response leaves widely separated possibilities indistinguishable.	Compare the required range, resources and attainable distinctions.
