Careful Planning & Design A variable is a factor that may change in an experiment. In most experiments, there is only one variable. Other factors must remain constant.
Controlled Experiment A control is used to provide a comparison against which the actual experiment can be judged.
Fairness Sample size, random selection, can be replicated, double-blind testing.
Sample Size As large a sample size as possible is tested.
Why Must You Use A Large Sample Size? To ensure individual differences do not matter.
Random Selection Reduces bias.
Can Be Replicated A replicate is an exact repeat of an experiment.
Why Is It Important To Repeat The Experiment? To ensure results weren't a once-off and are reliable.
Double-Blind Testing Neither the person being tested nor the tester should know who is receiving the placebo.
