How can you differentiate between accuracy and precision?

Back

Accuracy is about correctness (closeness to true value), while precision is about consistency (closeness of repeated measurements).

Front

What does a high precision but low accuracy measurement indicate?

Back

It indicates that the measurements are consistent but not close to the true value.
