Variables, Constants, Controls

Front

What is an independent variable?

Back

The independent variable is the one factor that is deliberately changed in an experiment to test its effect.

Front

What is a dependent variable?

Back

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

Front

What is a control group?

Back

The control group is the part of an experiment that does not receive the treatment or change, serving as a baseline for comparison.

Front

What is a controlled variable?

Back

Controlled variables are factors that are kept constant throughout an experiment to ensure that the results are valid.

Front

How do you identify the dependent variable in an experiment?

Back

The dependent variable is identified by asking what is being measured or observed as a result of changing the independent variable.

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 difference between qualitative and quantitative data?

Back

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

Front

Why is it important to have a control group in an experiment?

Back

A control group is important because it allows for a comparison to see if the independent variable has an effect.

Front

What is the role of constants in an experiment?

Back

Constants are the variables that are kept the same throughout the experiment to ensure that the test is fair.

Front

What is an experimental group?

Back

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