Differentiate between accuracy and precision

Here's the difference between accuracy and precision:

• Accuracy refers to how close a measurement is to the true or accepted value. It indicates the correctness of a measurement.
• Precision refers to how close repeated measurements are to each other. It indicates the reproducibility or consistency of a measurement, regardless of whether they are close to the true value.

For example, if the true weight of an object is 10 kg:

• A scale that consistently reads 9.9 kg, 10.0 kg, 10.1 kg is both accurate (close to 10 kg) and precise (readings are close to each other).
• A scale that consistently reads 9.0 kg, 9.1 kg, 9.0 kg is precise (readings are close to each other) but inaccurate (not close to 10 kg).
• A scale that reads 8.0 kg, 12.0 kg, 10.0 kg is neither accurate nor precise.
