Key Terminology in Psychology Experiments

Independent Variable:
- Controlled or manipulated by the experimenter.
- Represents the "If A happens" aspect of the experiment.
- Potential cause that researchers aim to evaluate its impact on the outcome.
Dependent Variable:
- Measures the effect or outcome of the independent variable.
- Demonstrates results of the hypothesis.
- Involves all groups being tested to assess the independent variable's influence, with a control group for comparison.
Confounding Variable:
- Irrelevant variables that can inadvertently influence the results.
- May include differences in participants, such as lifestyle or activities, affecting the outcome.
- Considered a potential cause less directly impacting the experiment's hypothesis.
Experimental Group:
- Group of participants that is exposed to the independent variable.
- Crucial for testing the hypothesis by observing if the independent variable produces predicted results.
- Provides data to demonstrate the cause-effect relationship essential for the experiment.
Control Group:
- Group subjected to all procedures except the independent variable.
- Helps isolate the independent variable's effect by comparing results against the experimental group.
- Essential for establishing a baseline that highlights the impact of the independent variable on the dependent variable.
