Identifying Independent Variables in Scientific Experiments

The video tutorial explains what an independent variable is, highlighting its role as a manipulated element in experiments. It discusses the relationship between independent and dependent variables, using the example of studying and test scores. The tutorial provides guidance on identifying independent variables by asking specific questions. It concludes with a brief discussion and directs viewers to additional resources for further learning.

What is another name for an independent variable?

• Manipulated variable

• Dependent variable

• Controlled variable

• Responding variable

In the context of an experiment, what is the role of an independent variable?

• It is the outcome measured by researchers.

• It is the variable that is changed or controlled by researchers.

• It is the variable that is influenced by other variables.

• It is the variable that remains constant.

How is the independent variable related to the dependent variable?

• The independent variable is influenced by the dependent variable.

• The independent variable is the result of the dependent variable.

• The dependent variable is the result of the independent variable.

• The dependent variable is unrelated to the independent variable.

In an experiment studying the effects of studying on test scores, what is the independent variable?

• Test scores

• Studying

• The number of students

• The difficulty of the test

Why is the independent variable considered 'independent'?

• Because it is not influenced by other variables in the experiment.

• Because it is the only variable that changes.

• Because it is the result of the experiment.

• Because it is the variable that is measured.

Who controls or changes the independent variable in an experiment?

• The participants

• The environment

• The researchers

• The dependent variable

Which question can help identify an independent variable?

• Is the variable being manipulated by the experimenters?

• Is the variable the result of the experiment?

• Is the variable being measured?

• Is the variable constant throughout the experiment?

What should you consider to identify an independent variable in an experiment?

• Whether it is the result of the experiment

• Whether it is manipulated by researchers

• Whether it is the variable that remains constant

• Whether it is the variable being measured

Where can you find more resources on research variables?

• In the introduction of the video

• In the conclusion of the video

• In the video description box

• In the appendix of a textbook
