Accuracy is a general concept while precision is more of a mathematical concept. On the whole though, the conceptual boundary between the use of the two words is kind of fuzzy. While accuracy means being correct and true in every detail, precision means being more exact and to the point in reference to a certain standard or method. For example, you can be accurate with your answer but you can be precise with the method of calculation.
Accuracy may also refer to the truthfulness of data and records. For example, you can have accurate demographic data of the people in a city. But, in this case precise would refer more to the inferences you have drawn from the accurate date in your possession about the demography of the city in question.
While accuracy refers more to the correctness of data, precision can also refer to greater detail in description of an object or concept. For example, accuracy can be kept in mind while collecting people’s opinion on the social system of marriage but precision will be required in detailing each case study and interpreting it.Both accuracy and precision can also refer to results obtained from mechanical objects like a compass and watch. For example, if you have tuned or set your watch and compass accurately, it will be able to give you the current time and direction at any given moment with precision.
Answer:
Accuracy is ‘the state of being correct’ and on the other hand precision is ‘the state of being exact.
Explanation:
Accuracy shows the nearness of the measurement with the actual measurement while precision shows the nearness of an individual measurement with other measurements.
Accuracy focuses on the errors caused by the problem in the instrument. while precision is concerned with errors, which occurs periodically with no recognizable pattern.
If the measurement is precise but inaccurate, the result will not be the expected one. And if the result is accurate but imprecise, then there are huge variations in the measurements. And finally, if the actual measurement is neither accurate nor precise, then the result would not have correctness and exactness at the same time.
