Discuss how systematic and random errors influence the precision and accuracy of an experiment.

Answer and Explanation:

For this we first define:

1. Systematic Error:

These errors arise as a result of faulty instrument or faulty design of the experiment. These are repeated errors through out the experiment.

2. Random Error:

These errors can not be predicted and do not result in repeated inaccuracies.

These can be referred to the variation in the measured readings.

3. Accuracy:

This term refers to the closeness of the recorded vales to the actual value or standard.

4. Precision:

This term refers to the closeness of the readings taken to each other.

The accuracy and precision in case of systematic error can not be enhanced by repeated measurements and in case of random error, accuracy and precision may be improved by careful experimenting and measuring at the experimenter's end.
