Experimental Design Overview

These flashcards cover key concepts from the experimental design overview, including definitions and roles of various components in a controlled experiment.

What is the purpose of a controlled experiment?

To test only one variable at a time, ensuring clarity of cause and effect.

What is the Independent Variable (IV)?

The change being tested in an experiment; it is graphed on the x-axis.

What is the Dependent Variable (DV)?

The change that is being measured in response to the independent variable; it is graphed on the y-axis.

What is the function of a Control Group in an experiment?

The control group does not receive the independent variable and serves as a baseline for comparison.

What are Constants in an experiment?

Conditions that are kept the same throughout the experiment to ensure valid results.

What does the term 'Experimental Group' refer to?

The group that receives the independent variable in an experiment.

What is a Hypothesis in the context of experimental design?

An explanation of a phenomenon that can be tested and includes the independent and dependent variables.

How does conducting multiple trials affect experimental validity?

It enhances the validity of the results by allowing for more reliable data.
