In the 4-Question strategy, Question 3 asks you to identify all potential manipulated variables in an experiment. Manipulated variables are the variables that you, as the experimenter, intentionally change or control to investigate their effect on the dependent variable.
When you consider only one manipulated variable as the independent variable in your experiment, all other variables are considered the controlled variables. Controlled variables are the variables that you keep constant throughout the experiment in order to eliminate their potential influence on the dependent variable. By controlling these variables, you ensure that any changes observed in the dependent variable can be attributed to the independent variable.
Listing all potential manipulated variables in Question 3 helps you identify the different factors or conditions you want to test in your experiment. By considering only one manipulated variable as the independent variable, you can specifically focus on how that particular variable affects the dependent variable while keeping all other variables constant.
