Accuracy Definition

Accuracy is defined as the degree of measured value close to its actual value. In other words, accuracy is also narrated as the degree of closeness of a measured value to the actual or known value.

Both accuracy and precision are used to measure the value of an object, however, the central difference between them is that accuracy is a degree of closeness between the measured and actual value, whereas precision is the degree where the same value is repeated every time.

For instance, if a measurement of a given object in a lab is 4.2 kg, whereas the known weight is 10kg, then the means the measurement is not accurate. Moreover, the precision is independent of accuracy. For more precise understanding of concept, check out a diagram listed below:
