Accuracy,Precision-Difference between Accuracy and Precision
This page compares Accuracy vs Precision and mentions difference between Accuracy and Precision.
Accuracy and Precision
• Definition: The accuracy of instrument is a measure of how close output reading is to
the correct value.
• Measurements which are close to each other are said to be precise.
Measurements can be any of the following.
• Precise but inaccurate
• Neither precise nor accurate
• Precise and accurate
Example: The three robots were programmed to place components at a particular point on a table. The target point was center of a circle as shown in the figure. The three different cases are depicted for these three robots as shown with their individual results. From this one can understand difference between accuracy and precision.
