A control is a duplicate setup of the experiment you are performing with everything identical except for the variable that you are testing.
Or, it is how the experiment would happen naturally, without you doing anything.
For example, if you are testing the effects of a certain medication on humans, you give half of the subjects the medication and the other half a placebo, which is a sugar pill that has no effect. The latter group is the "control group". Their purpose is to remove the psychological effect of taking the medication from the results of the experiment, so that the only variable remaining is the actual effects of the medication.
Constants are things that are kept the same for all trials, like making sure that every subject is taking a pill (and that they believe it is the medication in question, ever if it is only a placebo)

∙ 14y ago.... actually, they are not the same
the constant is something unchanged in an experiment. For example: sunlight, temperature, etc.
the control on the other hand, is the object you compare it to. So you want to see if coffee helps plants grow. In one, you add coffee, the other without. The one without would be the control.

∙ 10y agoA control is used in an experiment to show that the results of an experiment are actually the result of the condition being tested; on the other hand, constants are factors that do not change during an experiment.

∙ 12y agoA control is the variable that shows what woulod happen naturally without anyone interferring with it.
a standard for comparing results
a constant is the same amount kept throughtout the whole experiment (i.e, Water and sunlight on a plant project.)

∙ 13y agothe difference beetween a control and a variable is that a control is the standard outcome of a test is compared . and a variable is something in something in a experiment that can change.

Explain the difference between a constant and a coefficient?
A constant is just a number that remains same throughout, while a coefficient is one which is followed by one or more variables.
What is the difference between Kc and Kw for water?
Kc is the constant for concentration and Kw is the constant for water. Kc[h20] = [OH-][H+] which becomes Kw= [OH-][H+]
What is the difference between variable air volume and volume control damper?
vav is volume control damper.. vav is variable air volume..
Difference between calibrator control and standard?
controls differ from standards that they have same matrixas test specimen.
What is the difference between dissociation constant and equilibrium constant?
Equilibrium constants aren't changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature. The position of equilibrium is changed if you change the concentration of something present in the mixture. According to Le Chatelier's Principle, the position of equilibrium moves in such a way as to tend to undo the change that you have made.
What is the difference between constant and non-constant motion?
Acceleration is the difference between constant and non-constant motion.
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
What is the difference between constants and control?
A control receives no Independent Variable (or IV) and a constant stays the same throughout an experiement.
Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant
What is the difference between variable constant and control?
A constant is always fixed and won't change in an experiment. The control is the standard that you are testing against to see how experiment outcomes change when the testing factors are altered.
What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
What the difference between a variable and control?
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
What is the difference between ordinary prism and constant deviation prism?
difference between ordinary prism and constant deviation prism
Difference between attenuation constant and phase constant?
nothing
What is the difference between a control variable and a control treatment?
what is the difference between a variable and a control
What is the difference between feedback and control?
difference between feedback and control
What is the difference between an experimentation variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
