Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
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 is how close you are to your expected value and precision is how close together your experimental values are.
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.
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.

have distinctly different meanings
''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.
Generally, this term is called ACCURACY.

Then they have precision but not accuracy.

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.
Accuracy is how close you are to your expected value and precision is how close together your experimental values are.
No. accuracy is a measure of how close the measurements are to the true 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.
Accuracy refers to how close a measured value is to an excepted value. Precision refers to how close a series of measurements are to one another For example, if your experimental value is 15.63 and your values are... 12.84 13.02 12.96 They would be precise because they are close to one another but not accurate because they're not even close to the experimental value
