Accuracy and Precision are two types of measurements that illustrate how close one is to the target or goal. Accuracy is used to determine how close one is to the true value of measurement, while precision implies how close the measured values are to one another.
|Precision implies the closeness of two or more measurements to each other||Accuracy implies how close a measurement is to the correct value|
|Measurement can be precise but not accurate||Measurement can be accurate but not precise|
|Needs several measurements to determine||Can be determined with a single measurement|
|Precision may be affected by random error||Accuracy may be affected by systematic error|
|Multiple Factors||Single Factor|
