Accuracy Vs Precision Dart Board. Similarly when they are spread out it is low precision. Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured.
If darts are closed to each other then it is high precision. Error is shown as the dif-ference between a single dot or value and the center of the board. In other words accuracy describes the difference between the measurement and the parts actual value while precision describes the variation you see when you measure the same part repeatedly with the same device.
Precision measures how close measurements are to each other.
Precision can be broken down further into two components. Precision measures how close measurements are to each other. Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured. Bias is shown as the difference between the middle of several dots and the center of the board.
