Controlled variables are quantities that a scientist wants to remain constant, and she or he must observe them as carefully as the dependent variables. For example, in the dog experiment example, you would need to control how hungry the dogs are at the start of the experiment, the type of food you are feeding them, and whether the food was a What Are Dependent, Independent& Controlled Variables?
By Alexander White; Updated April 24, 2018 Progress in science depends on wellplanned experiments that yield communicable results. The Variable Frequency Drive is a particular kind of adjustablespeed drive that is used to control the speed of an AC motor.
In order to control the motor's rotational speed, a Variable Frequency Drive controls the frequency of the electrical power supplied to it. Sep 15, 2011 Scientific Variables Alex Koning.

Variable Any part of an experiment that can vary. Independent Variable The part of the experiment that is manipulated or changed by the scientist or person performing the Manuale sclerometro controls and variables. Control and Experimental Variables Control Variablesthe variables that you control (dont change) in an experiment.
The control variables are all other variables than the experimental variable.
