These two qualities are quite different. First off, the concept of 'true value' should be accepted. This is the value to which a large number of measurements tend. Preferably measurements made by different experimenters and by different methods.
'Accuracy' is the closeness to which an individual measurement approaches the 'true value'.
'Precision' is closely related to resolution. And one may have a very precise answer, but still be well away from the true value. Resolution is the number of digits in the answer - and may well have an illusory value.
Precision and accuracy do not mean the same thing in science. Precision refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the correctness of a single measurement. It is determined by comparing the measurement against the true or accepted value.
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
the precision of the least precise measuement

the answer is you have to use the right instrument on somthing to get the right answer
accuracy. precision how closely the group of data are in relation to each other
In general it could - particularly if the precision of the scale is not matched by the accuracy of the data in the table.
Precision and accuracy do not mean the same thing in science. Precision refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the correctness of a single measurement. It is determined by comparing the measurement against the true or accepted value.
Poor precision. Precision refers to the consistency of repeated measurements, while accuracy refers to how close a measurement is to the true value. If a speedometer consistently shows a speed that is off by a fixed amount from the actual speed (e.g., always reads 5 mph higher), it has poor accuracy. If it fluctuates widely even for the same speed, it has poor precision.
precision
So accuracy is how close the mean is to the true value. Precision is how close all your values are to each other. If you have repeatable results you will see this straight away. Spiking samples with known amounts is a great way to find out if you have as much as you think you have i.e. checking the accuracy
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
Accuracy and precision are synonyms. They both mean without error, they are exactly right, No more and no less.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
Precision is a writer's attention to accuracy in world choice.
