VARIABLES OF AN EXPERIMENT---OCTOBER 24, 2024

Front

What is an independent variable in an experiment?

Back

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

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment to see how it is affected by changes in the independent variable.

Front

What does it mean to keep variables constant in an experiment?

Back

Keeping variables constant means that certain factors are not changed throughout the experiment to ensure that the results are due to the manipulation of the independent variable.

Front

In a line graph, where is the independent variable plotted?

Back

The independent variable is plotted on the x-axis.

Front

In a line graph, where is the dependent variable plotted?

Back

The dependent variable is plotted on the y-axis.

Front

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

Back

The control group serves as a baseline to compare the effects of the independent variable, ensuring that the results are due to the variable being tested.

Front

How do you identify the dependent variable in an experiment?

Back

The dependent variable is identified as the variable that is measured or observed in response to changes in the independent variable.

Front

What is the role 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 increases the reliability of the results and helps to confirm that the findings are consistent.

Front

What is a variable in the context of 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.
