Variables that have been supremacyled in this way are called control variables. There are many forms of contro lled or  in disco biscuittional experiments.

Each guinea pig develops their consume specific, important controls. Controlled variables are the variables that are input to the control system. response rate is the dependent variable and everything else that can change the resp onse rate must be controlled (kept constant)! so that you besides measure the effects of concentration. Variables that need to be controlled in this sheath implicate temperature, catalyst, surface area of solids, and pressure. If not controlled, they complicate the experiment and hence, the testing is less valid. For example, a control variable could be meter or mass or each marble had ten minutes to dissolve in acid. 2-CONDITION VARIABLE A condition variable indicates an event and...If you want to get a unplumbed essay, order it on our website: BestEssayCheap.com
