Principles of scientific treatment:

Good experimental design allows for valid comparison between treatments and also allows us to examine our hypothesis and not the interaction of many factors. The 4 main key factors required are control, randomisation, standardisattion and replication

Accuracy: How close the experimental results are to the 'true value'; often reflected in the perentage error
Reliability: for an experiment to be reliable it must have been repeated several times and similar results obtained. Repetitions reduce the impact of random error however it does not improve reliability. Relibility is also used todescribe sources of information such as primary and secondary
Validity: how relevant the procedure is to the question being investigated

Diagrams: Use pencil and ruler
