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..

What is the difference between the accuracy of measurements and the precision of measurements?

Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.

What is the difference between accuracy and precision and which is most important to scientific measurement?

Both accuracy and precision are important to scientific measurement. I'll try to explain the difference with a couple of illustrations. I should start by saying, sometimes the words are used interchangeably but they shouldn't be. I consider precision to mean resolution. That is how fine/small a reading you can get.Assume an electronic thermometer (digital display) can display answers to the nearest one hundredth of a degree. But, the thermometer isn't able to measure with that accurately. Maybe it's only accurate to the nearest whole degree. In this case the precision is greater than is supported by the accuracy of the device.Now take the opposite case where the thermometer is able to measure temperature accurately to one hundredth of a degree but the instrument can only display whole degrees. In this case the precision does not support the accuracy.Ideally the accuracy and precision of an instrument are the same but often that's not the case.


What is the difference between accuracy and precision and which one is more important to scientific measurement?

To be accurate is to be correct, for example, if you say it will rain tomorrow and it does rain tomorrow, then your prediction was accurate. Precision means to give a finely detailed measurement or observation, rather than an approximation. In the case of the weather prediction, a precise prediction might be on the order of, it will rain a total of 1.68 inches of rain, tomorrow. Such a prediction might or might not be accurate, but if it is, then it is also precise, much more precise than merely predicting that it will rain. Precision includes the concept of accuracy. An observation that is precise but inaccurate is useless; precision is only valuable when it is also accurate. Scientists cannot really choose between accuracy and precision since both are necessary for science to succeed, but accuracy is more fundamental. Something that is approximately correct is worth more than something that is very detailed, but wrong.


Do precision and accuracy mean the same thing in science?

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.

What are accuracy and precision and what is the difference between accuracy and precision?

Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.


What is the difference between acurtate and precise?

An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.


What is the difference between accuracy and presicion?

Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.

what is the difference between accuracy and precision?

''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.

Does the speedometer have poor precision or poor accuracy?

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.


What differecne between the accuracy and precision?

Accuracy is how close the value that is measured to a true or standard value. While precision is referred as the degree of nearness of the measured values to one another in a repeated same value.
