Accuracy vs Precision [SL IB Chemistry]
Показать описание
Accurate - your data is close to expected/theoretical value (even on average)
Precise - your data is close to itself
ANSWERS:
Accurate and Precise - data is close to zero and not widely spaced.
Precise not accurate - data clustered but not near zero = systematic error
Accurate not Precise - average is near zero, but data broadly spaced = random error
Neither accurate nor precise
Precise - your data is close to itself
ANSWERS:
Accurate and Precise - data is close to zero and not widely spaced.
Precise not accurate - data clustered but not near zero = systematic error
Accurate not Precise - average is near zero, but data broadly spaced = random error
