Control variables refer to variables whose effects on an outcome variable are statistically adjusted in order to estimate independent effects of an explanatory variable. In its conventional usage, the term is limited to variables that are actually observed. This article discusses methods of controlling ...
Control variablesare crucial to scientifically sound experiments and studies. Acontrol variableis sometimes simply called acontrol.Both terms are widely used in science and statistics. Why arecontrol variablesimportant? Science is messy. We like to think of experimentation as a simple process of “cha...
In biology, what is a dependent, independent and control variables when designing an investigation?Types of Variables:In science, a variable is a detail or condition that can be controlled or perhaps altered in some way. In scientific investigations, studies are designed that...

the most effective in this case. The same weightage has been given to all the control variables; therefore, the output weights (MPC parameter) of all the control variables are 1. The value of rate weight for every control variable is 0.1. It should be noted that in case of the MPC, ...
