Via controlled experiments or pertinent observations
Kinds of variables:
Experiments of classical design
Individuals studied divided into two groups» Experimental group
» Control group
How does science really work in today’s world?
Exhaustive literature search + observations hypothesis
Prediction Write a proposal, design experiment Get money $$$$$ Revise proposal based on $$$ Experiment/collect data Statistics Write manuscript of results Publish or perish
What happens if all of our experiments fail to negate our hypothesis?
What if workers in other parts of the community, county, state, country, or world also fail to negate your hypothesis?
To Prove or Not to Prove Experimentation can either support or reject a
hypothesis. Experimentation can never prove a hypothesis
100% correct. – why?
After each each experiment we need to re-evaluate our results and observations to either make changes in our hypothesis or more likely design a new experiment.
