STRIVING FOR ACCURACY

Accuracy can be receptive, expressive or self-contained. A person might be listening, or reading accurately. Someone can speak, write, or play music or dance accurately. One may also think accurately. Accuracy and precision are slightly different. Accuracy invloves an external standard. For example, if you measure a weight of 3.2 kg for some object, but the actual or known weight is 10 kg, then your measurement is not accurate. Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh an object five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise.
