Independent variable
experimental control
the control for multiple variables in a experiment
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
experimental control
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.

experimental control
You establish a controlled variable from which you can compare your results from your experimental variables.
The variables that must remain the same between the control group and experimental group is are called controlled variables, and include everything except the experimental variable.
Independent variables. If the treatment has no effect , the dependent variables for both the control and experimental group may be the same. cw: In some studies, there is no specific control group. For instance, in a drug study where subjects are given a random amount of the drug (from 0 up to some presumed safe level) then you cannot easily tell what the "experimental" group is -- you can't compare everyone else to the two subjects who got a placebo (0 mg/kg). You can tell whether the treatment is having a linear effect, etc.
