The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
A dependent variable is one that changes based on changes of the independent variable. Or we can say it depends on whatever happens to the independent variable.
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,

It depends on the relationship, if any, between the independent and dependent variables.
In order to be certain that the changing of the independent variable directly affects the dependent variable, a control must be taken where the independent variable is not changed-this ensures that whatever happens to the dependent variable happens because of the independent variable, and is not something that would happen anyway.
The Temperature is the Independent Variable (50 degrees, 100 Degrees etc.) Whatever happens as a result of the temperature change is the dependent variable.
Independent variable is what you change in the experiment group. Dependent variable is what happens because of the independent variable. It has to be measurable in degrees, inches, or other such measurements.
In an equation like y = mx + b, such as y = 3x + 2, x is the independent - YOU put in the x. y is the ANSWER you get, depending on what you used for x. To test, do exactly that - you choose what to do for your independent variable, and see what happens for the y. Works for both math and science. Change the independent variable, and compare how your dependent variables change depending on what changes you made to the independent.
The dependent variable.
The independent variable is also known as the experimental variable. It is the one variable that is manipulated or allowed to vary. All other variables are kept constant. For example, if you want to determine the relationship between mass and acceleration, you would vary the mass and it would be the independent variable. You would then measure the acceleration that occurs with different masses, which would be the dependent variable.
