Experimental Method and Design - Aspects to Consider

WHAT?
WHY?

A _control_ must be included
A standard for comparison

State what should be_ observed_
measuredYou have to know what you
intend to record

Choose an appropriate method
of recording observations or
_data_ To organise information usefully

Choose a method of_ collation_
of data eg. graphs To make it easier to interpret

The experiment must be able to
be _replicated_ or reproducedThere must be consistency in the
design

The experiment must be_ repeated_
This increases reliability of
results/outcomes, by reducing
impact of variation - if the
experiment were to be carried
out only once or twice,
the first set or results could have been
atypical, through chance or error
