Explain how your
processed data
supports or r ejects
your hypothesis.

C-iv and v Evaluation of Method and Extension
Suggestion for
improvement
Discuss the changes to the
method or the equipment used
that can improve the quality of
the data (performing a better
method using better equipment.
Significance
Why the method is improved
State whether the source of error identified
make the data less reliable, or completely
unreliable
Explain how the changes proposed
make the data collected more
reliable?
Suggested Extension
Relevance of Extension
State whether expanding or reducing the range gives you more detail about the trends in the data.
Describe any database or other method that you can use to compare our results to. Will changing the values of the
controlled variable results in different trends?
