i received this information from wikipedia. http:/en.wikipedia.org/wiki/Experiment hope that helps :)
A scientist helps a colleague do a better experiment by
The Independent Variable (I.V.) is what the scientist changes. The Dependent Variable (D.V.) is the outcome of the I.V. There can only be one I.V. in a controlled experiment if you want accurate results
The dependent variable is the variable that can change in an experiment.
the part of an experiment that changes is called the variable.
A factor that can be changed in an experiment is called an independent variable.
The factor changed is the independant varible, the thing that the scientist can change each time they run the experiment. The control is the part of the experiment that the scientist determines stays the same. Ex. They have one person eat a milk chocolate and a dark chocolate and then ask which one they like. The person is the control because it stays the same. The chocolate is the independant varible because the type changes.

Yes, the one factor that a scientist changes during an experiment is also called an independent variable.

changes result!
