Dr. Leady Chapter 1: Scientific Method January 11, 2016 *REWRITTEN FROM NOTES GIVEN BY INSTRUCTOR* Scientific Method Observation Hypothesis Predictions Experiment/Tests Theory Hypothesis VS Theory Hypothesis- Reasoning or explanation from an observation; must be able to test Theory- It has support for its reasoning; has not been shown/proven to be false Independent, Dependent, and Control Variables Independent- The variable that is changed Dependent- The variable that is measured Control- The variables that are kept the same or constant in each treatment Treatment VS Control Group Treatment- The group that receives the treatment; group should all be similar in their controlled variables, such as: age, height, weight, etc. Control- The group that does NOT receive the treatment; group also gets the same treatment as the treatment group, but not the treatment. Example: If it was being tested that this “ pill” cured AIDS. The treatment group would get the “pill” that potentially cured AIDS and the control group would get what is known as “placebo” which is a sugar pill. This would test to see if the “pill” could potentially cure AIDS. Experiment Advice The more times the experiment is tested, the better The more subjects/larger involvement of the experiment, the better Only changed one variable at a time; causes better results
