Answer:
Accuracy and precision are both important concepts in measurement, but they refer to different aspects of the measurement process.Accuracy refers to how close a measured value is to the true or expected value. In other words, accuracy is a measure of how well a measurement reflects reality. A measurement can be accurate even if it is not precise, as long as it is close to the true value.Precision, on the other hand, refers to the level of consistency or reproducibility of a set of measurements. In other words, precision is a measure of how well a measurement can be replicated. A measurement can be precise even if it is not accurate, as long as the values are consistent and repeatable.To illustrate the difference between accuracy and precision, consider the example of a dartboard. If a person throws several darts and they all land in the same spot, that person has high precision. However, if the darts all land far away from the bullseye, they have low accuracy. If a person throws several darts and they are spread out across the board, that person has low precision. However, if the darts are all clustered around the bullseye, they have high accuracy.In summary, accuracy is a measure of how close a measurement is to the true value, while precision is a measure of how consistent or reproducible a set of measurements is.
