Definition Of A Controlled Variable. However the control variable is not part of an experiment but it is important because it can have an effect on the results. The controlled variable is kept constant so the changes in other variables can be observed more easily. Controlling this variable is the primary function of process control. It is important to ensure that all these possible variables are isolated because a type III error may occur if an unknown factor influences the dependent variable.
In simple words a controlled variable is any element quantum or feature in a given experiment or equation that can be fixed or would not be changed at all during the course of the experiment or equation. Evidence gathered during uncontrolled studies can thus be inconclusive. The controlled variable is kept constant so the changes in other variables can be observed more easily. A variable is controlled when its influence on the other variables in the model is held constant. It is important to ensure that all these possible variables are isolated because a type III error may occur if an unknown factor influences the dependent variable. Controlled Variable The controlled variable is a process parameter being controlled.
The element its value or quantum can be changed but it would not be changed.
Controlled variables are often referred to as constants or constant variables. A control variable in computer programming is a program variable that is used to regulate the flow of control of the program. The controlled variable is not a constant. A controlled variable is one which the scientist holds constant controls during an experiment. Evidence gathered during uncontrolled studies can thus be inconclusive. Controlling this variable is the primary function of process control.
