Step 4 – Analysis & Organize Data
Step 5 - Conclusion

4. Step 1 Identify the problem Begins with an observation

5. Step 2
Formulate a Hypothesis
An EDUCATED guess
If … Then… statement

6. Practice
Rewrite the following observation into a formalized hypothesis

Test group
One factor is changed

8. Standard everything else is measured against
Controlled Group
Standard everything else is measured against
Nothing is changed
Ex: placebo or sugar pill

9. Step 4 Collecting and organizing data
Reflected in a table, graph, or chart

10. Step 5
Conclusion
Support or reject your hypothesis based on your results (findings)
