Overview

This video explains the concepts of dependent and independent variables in the context of experiments and research. It defines each variable, illustrates their relationship as cause and effect, and provides multiple examples to clarify their application.

Key takeaways

• Independent Variable (IV): This is the variable that is changed or controlled by the experimenter to observe its effects on another variable. It is considered the "cause."
• Dependent Variable (DV): This is the variable that is investigated and measured. It is expected to change in response to the independent variable and is considered the "effect."
• Cause and Effect Relationship: The independent variable is the cause, and the dependent variable is the effect.
• Examples Provided: The video uses examples such as pizza price (DV) depending on size (IV), fruit consumption (IV) affecting physical resistance (DV), and paracetamol dosage (IV) affecting fever reduction (DV) to illustrate the concepts.
• Other Names: The independent variable can also be called a controlled variable or predictor variable. The dependent variable can be referred to as an experimental variable, measurement variable, or response variable.
