A variable that is not affected by the size of the subject (or experimental unit).

An independent variable is what you change during an experiment, and a dependent variable is what gets changed. for example, if you are monitoring temperature vs size of plants. Everyday you change the temperature, and then record the size of the plants. Therefore, the temperature is the ind. variable and the size of the plants is the dep. variable.
Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
The independent variable.
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
An independent variable is a factor that doesn't rely on anything, unlike the dependent variable (which relies on the independent variable). The most common independent variable is time.
