What are experimental variables?
an independent variable that is manipulated by the researcher to determine its relationship to or influence upon some outcome or dependent variable.
What are the 3 experimental variables?
An experimental inquiry typically has three main types of variables: an independent variable, a dependent variable and controlled variables. We will look at each of these three types of variables and how they are related to experimental inquiries involving plants.
How do you find the experimental variable?
Remember: Your Independent Variable must be something you can systematically present to one group but not present in the same form to the other group. Your dependent variable must be something you can reliably measure, test or observe in each of your participants.
