What does “Accuracy, precision and uncertainty” actually mean in Experimental Skills, and why does it matter for NEET?
Accuracy means closeness to the accepted value; precision means repeatability. Repeated measurements can reduce random uncertainty but cannot remove a systematic calibration error.
In simple words: Accuracy means closeness to the accepted value; precision means repeatability. Repeated measurements can reduce random uncertainty but cannot remove a systematic calibration error. Getting Accuracy, precision and uncertainty clear matters because NEET questions on Experimental Skills usually test this idea directly, not just a formula you memorised.
Key point
Accuracy, precision and uncertainty
Common mistake
calling tightly clustered but shifted readings accurate.
Memory tip
tight cluster is precise; correct centre is accurate.
