What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

Front

What does it mean to prevent bias in an experiment?

Back

Preventing bias means ensuring that personal opinions or preferences do not influence the results of the experiment.

Front

What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the significance of replicating an experiment?

Back

Replicating an experiment helps to confirm the results and ensures that they are reliable and not due to chance.

Front

What is the role of a control group in an experiment?

Back

A control group is used as a standard for comparison; it does not receive the experimental treatment.

Front

What is an experimental group?

Back

An experimental group is the group in an experiment that receives the treatment or condition being tested.

Front

Why is it important to record data in an experiment?

Back

Recording data is crucial for analyzing results, drawing conclusions, and verifying the experiment's findings.

Front

What is a conclusion in the context of an experiment?

Back

A conclusion is a summary of the results of an experiment, explaining whether the hypothesis was supported or not.
