What is an Independent Variable (IV)?

Back

An Independent Variable is the factor that is changed or manipulated in an experiment to observe its effects.

Front

What is a Dependent Variable (DV)?

Back

A Dependent Variable is the factor that is measured or observed in an experiment, which is affected by the independent variable.

Front

What is a Hypothesis?

Back

A Hypothesis is a testable statement predicting the relationship between the independent and dependent variables.

Front

Why is it important to have only one independent variable in an experiment?

Back

Having only one independent variable helps to isolate its effects and ensures that the results are valid.

Front

What is a Control Group?

Back

A Control Group is a group in an experiment that does not receive the treatment or independent variable, used for comparison.

Front

What is a Testable Question?

Back

A Testable Question is a question that can be answered through experimentation and observation.

Front

What is the purpose of a Variable in an experiment?

Back

Variables are factors that can change in an experiment, and they help to determine the relationship between the independent and dependent variables.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numbers and measurements.

Front

What is a Conclusion in an experiment?

Back

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