What Are Some Examples Of Independent And Dependent Variables

Rotation speed measured in revolutions per minute dependent variable.

It s what changes as a result of the changes to the independent variable. The dependent variable is the variable being tested and measured in an experiment and is dependent on the independent variable. Extraneous variables are undesirable variables that influence the relationship between the variables that the experimenter is observing.
