Question

Distinguish between accuracy and precision.

Answer 1

No.	Accuracy	Precision
i.	Accuracy refers to the nearness of the measured value to the true value.	Precision refers to the closeness of multiple readings of the same quantity.
ii.	Accuracy represents the correctness of the measurement.	Precision represents the agreement between two or more measured values.
iii.	Accuracy is expressed in terms of absolute error and relative error.	Precision is expressed in terms of absolute deviation and relative deviation.
iv.	Accuracy takes into account the true or accepted value.	Precision does not take into account the true or accepted value.
v.	Accuracy can be determined by a single measurement	Several measurements are required to determine precision.
vi.	High accuracy implies a smaller error.	High precision implies the reproducibility of the readings.
