Explain the difference between the precision and accuracy of an experiment.

Accuracy is defined as the extent up to which the calculated value is close to the actual value.

Precision is calculated after several experiments, it is the repeatability of the result. It measures the extent up to which the result is close to each other.

Closer the measurement more accurate is the measurement.

Less is the variation from the exact value more is the Precision.
