Precision refers to how close one's results are to each other. Accuracy on the other hand refers to how close one's results are to the true value. Think of a target, precision would be how tight the grouping of the arrows was, while accuracy would be how close one was to the bullseye. To clarify, being precise does not equate to being accurate, because while one might obtain data that are all very close, these data might not be near the true value.

No, precision and accuracy have different meanings in science. Precision refers to how close measurements are to each other, while accuracy refers to how close measurements are to the true or accepted value. A measurement can be precise but not accurate, or accurate but not precise.
precision
Precision refers to how close repeated measurements are to each other, indicating the level of consistency or reproducibility in the results. A high level of precision means that measurements are closely clustered together, demonstrating a low degree of variability in the data.

Standard deviation gives a measure of precision, not accuracy. It quantifies the amount of variation or dispersion of a set of data points around the mean. Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other.
A precision unit of a ruler typically refers to the smallest increment of measurement marked on the ruler. For example, a ruler with millimeter markings has a precision unit of 1 millimeter.
Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.
Precision refers to the consistency of measurements, with high precision meaning that repeated measurements yield similar results. Accuracy, on the other hand, refers to how close a measurement is to the true or accepted value. In practical terms, precision pertains to random errors in measurements, while accuracy accounts for systematic errors.
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.
Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close repeated measurements are to each other. High accuracy means that a measurement is very close to the true value, while high precision indicates that repeated measurements are consistent and close to each other.
