independent variable
used as an experiment to show that the result of an experiment are a result of conduction being tested.
An unexposed subject is the "control" for the experiment. The purpose is to establish an idea of what would normally occur outside the testing procedure. Similarly, in human tests, an inactive "placebo" is given to some subjects to verify that the changes occur independently of the psychosomatic (belief-driven) effects. In a "double blind' experiment, the person distributing the medication also does not know whether any particular individual is receiving the actual drug or a placebo. This is hidden in coded form until the results are recorded.
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.
An oxygen meter measures the percentage of oxygen in the air being tested.
When the leaves fall down the supply of chlorophyll is stopped
Yes. The dependent variable is the variable that is being measured during the experiment.
No, a hypothesis is. A variable is the thing being tested in the experiment.
The dependent variable is the variable that can change in an experiment.

Independent variable ! :)
The factor being tested is the dependent variable.

The factor that is being tested in an experiment is called a variable. The factor that is measured or observed is called the dependent variable.
