To ensure results are reliable the experiment should be

• Done once

• Repeated

• Done as exactly the same as the method outlines

• Repeated if necessary

A reliable experiment produces results which

• vary greatly

• are different from sample answers

• are not consistent

Repetition _______________ the effect of outliers and allows them to be removed.

• increases

• minimises

• equals

• justifies
