A measure that demonstrates the effect of the independent variable.

An experimental variable controlled or manipulated by the experimenter. (correct)

A group of participants that is exposed to the independent variable.

Variables that are irrelevant to the hypothesis being tested.

The dependent variable is the effect.

Study Notes

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.
