AP PSYCHOLOGY

Detailed explanation-1: -An organized procedure for testing a hypothesis; tests the effect of one thing on another under controlled conditions. Educated guess using what you know and what you observe. It is a prediction that can lead to experimentation. A factor that, as it changes, affects the measure of another variable.

Detailed explanation-2: -An experiment tests the effect of one thing on another using controlled conditions.

Detailed explanation-3: -When conducting an experiment, a control is an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured. Controls are typically used in science experiments, business research, cosmetic testing and medication testing.

Detailed explanation-4: -The experimental method involves the manipulation of variables to establish cause and effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups. An experiment is an investigation in which a hypothesis is scientifically tested.

Detailed explanation-5: -A good example would be an experiment to test drug effects. The sample receiving the drug would be the experimental group while the sample receiving a placebo would be the control group. While all variables are kept similar (e.g. age, sex, etc.) the only difference between the groups is the taking of medication.
