The independent variable is the type of variable that the researcher has control over and wishes to manipulate in an experiment. It is the variable that is being tested to see if it has an effect on the dependent variable. The dependent variable is the variable that is being measured or observed in response to changes in the independent variable. Extraneous and control variables are also important in an experiment, but they are not the type of variable that the researcher wishes to manipulate. Complex variable is not a common term used in experimental design.
