Errors

Question 1

Systematic errors

Answer 1

that cause the same incorrect result each time.

• These results are PRECISE but not ACCURATE – they give the same inaccurate result each time
  These can be reduced by calibrating instruments (or replacing/repairing faulty ones)

Question 2

Random Errors:

Answer 2

Unpredictable errors that differ each time a measurement is taken.

• These results are NOT precise and not accurate.
  Random errors can be reduced by replicating experiments, testing a bigger sample size or using a
  more accurate instrument or method to take measurements
