5. Goal of a Hypothesis
The goal of a hypothesis is to help explain the focus and direction of the experiment or research.

Identify what variables are used

6. Parameters of a Good Hypothesis
In order to be a good hypothesis that can be tested or studied, a hypothesis:
Needs to be logical
Must use precise language
Should be testable
A hypothesis is usually written in a form where it proposes that if something is done, then something else will occur.

7. Remember Sometimes research is needed before making a hypothesis.
A hypothesis is an educated guess. It simply gives us a direction to go with the investigation.
NEVER go back after testing and change your hypothesis.
Science has been based on lots of mistakes. It’s through our mistakes that we learn!
