Verified step by step guidance

Understand the context of an experiment: In psychological research, experiments are conducted to determine the cause-and-effect relationship between variables.

Identify the types of variables: In an experiment, there are typically independent variables, dependent variables, and sometimes confounding variables.

Define the independent variable: This is the variable that the experimenter manipulates or changes to observe its effect on the dependent variable.

Differentiate from other variables: The dependent variable is what is measured in the experiment, and confounding variables are other factors that might affect the outcome.

Recognize the role of the independent variable: It is crucial because it is the presumed cause in the cause-and-effect relationship being tested in the experiment.
