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.
Any variable can be declared as the independent variable, then the other would be the dependent variable. However, it is quite common to arbitrarily define y as the dependent variable - a variable that depends on x.
The independent variable.
The independent variable and the constant(s).
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.

Independent variable(manipulated variable) is a variable that is changed delibertly by the experimentor. *most of the time the first part of a projects question is the independent variable.

Changes in the independent variable are independent of changes in any other variable,
The independent variable is the variety of baits.

The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
The term 'independent variable' is normally used to refer to the variable that you are investigating in an experiment. A common colloquial definition is 'The variable you change' which is helpful, but not always clear. AQA (A UK examination board) defines it in the following way 'The independent variable is the variable for which the values are changed or selected by the investigator' Aims of experiments are often written in the form 'How does X affect Y?' X would be the independent variable and Y the dependent variable.
