In a kingdom there was an excellent archer. The ruler was jealous of his archery skills, so he decided to put his skills to test. The archer was asked to shoot an apple which was placed on his son's head or else his son will be killed. The archer always used his trusted bow.
Case 2: The archer was really confident but the ruler hired a thief to steal his bow and replace it with a defective one which is slightly bent to the side. This time when the archer shot from the new bow he always hit the same spot but slightly deviated from the apple. In this case the archer is:
Precise
In this case the archer hits the same spot multiple times but not the apple. This means that his shots are precise but not accurate.
Precision by definition is the closeness of various measurements for the same quantity. If the average of different measurements is close to each other and hence closes to their actual value, the measurement is said to be accurate. In simple words we can say that the measurement is precise when the outputs we get in multiple repetition of an experiment are close to each other. But, they need not be close to the actual value.
