Independent and Dependent Variables

Front

What are independent and dependent variables?

Back

Independent variables are the factors that are manipulated or changed in an experiment, while dependent variables are the factors that are measured or observed in response to changes in the independent variable.

How are variables described in a hypothesis?

Back

Variables in a hypothesis are typically described as relationships between independent and dependent variables.

Front

What is a control variable?

Back

A control variable is a variable that is kept the same throughout an experiment to ensure that the results are due to the independent variable.

Front

In an experiment, what is the dependent variable?

Back

The dependent variable is the outcome or response that is measured in an experiment, which is affected by the independent variable.

Front

What is the independent variable in an experiment?

Back

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

Front

Give an example of a dependent variable in a temperature experiment.

Back

In an experiment where different materials are heated, the dependent variable could be the temperature of the materials after a set time.

Front

What does it mean to control a variable in an experiment?

Back

Controlling a variable means keeping it constant to ensure that it does not influence the outcome of the experiment.

Front

In the context of a graph, what is a dependent variable?

Back

In a graph, the dependent variable is typically plotted on the y-axis and represents the data that is being measured.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe how it affects the dependent variable.

Front

How can you identify the dependent variable in a scientific question?

Back

The dependent variable can often be identified by looking for the outcome or effect that is being measured in response to changes in the independent variable.
