In an experiment, what is the independent variable?

Back

The independent variable is the factor that is manipulated or changed by the experimenter to observe its effect on the dependent variable.

Front

What is a control group in an experiment?

Back

The control group is the group in an experiment that does not receive the treatment or variable being tested, serving as a baseline for comparison.

Front

What is an experimental group in an experiment?

Back

The experimental group is the group in an experiment that receives the treatment or variable being tested.

Front

Can you have more than one independent variable in a controlled experiment?

Back

False. A controlled experiment should only have one independent variable to ensure that the results are due to that variable alone.

Front

What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a testable prediction about the relationship between variables, guiding the direction of the experiment.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types and can affect the outcome of an experiment.
