Design controls that actually isolate variables

Steps

1. 1List confounders specific to THIS setup, not textbook generics
2. 2Include negative control answering 'does anything respond?'
3. 3Include positive control proving assay sensitivity that day
4. 4Randomize sample placement/handling order where physical effects exist
5. 5Blind analyzers to condition labels during measurement
6. 6Pilot blind-unblinding differences once; document what you learned

Common Pitfalls

• ▲All treated samples run on same day/batch plate
• ▲Analyst guessing conditions from subtle file naming
