	•Step 1. Make observations about the world. Science doesn't happen in a vacuum.
	•Step 2. Construct a Hypothesis. State clearly the aims and objectives of your study. Formulate the Null Hypothesis.
	Formulate the Null Hypothesis.
	•Step 3. Design the experiment.
	This is the stage at which you should seek the advice of a statistician
	regarding the hypothesis, sample selection, sample size, choice of measurements, and the type of analyses and statistical tests to be used. Failure to consult properly at this stage may mean that any work that you do may be a waste of time. Do not take that chance!
	•Step 4. Conduct the research.
	•Step 5. Analyze the data both observationally (do the numbers make sense?) and statistically.
	•Step 6. Interpret the results (draw inferences) and write your report (for marking or for publication). Work that is not marked or published may just as well never have been completed.
	•Step 7.Bask in the glory of a job well done.
