Questions and Answers
What is the purpose of an aim in an experiment?
What is the purpose of an aim in an experiment?
To find out if, how, or which independent variable affects the measured variable.
What is a control set-up in an experiment?
What is a control set-up in an experiment?
A set-up used to compare and confirm that any difference in the dependent variable is solely due to the independent variable.
What is the role of controlled variables in an experiment?
What is the role of controlled variables in an experiment?
They prevent inferred factors from affecting the results.
