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.
A control is a variable that can be changed or manipulated in an experiment to test its effect on the outcome, while a constant is a variable that remains the same throughout the experiment to serve as a baseline for comparison. Controls help determine causal relationships, while constants ensure that external factors do not influence the results.

∙ 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.

What are difference between constant immersion hydrometer and constant weight hydrometers?
Constant immersion hydrometers are designed to be fully submerged in the liquid being tested, providing readings based on the buoyancy principle. Constant weight hydrometers are initially weighed in air and then in the liquid, with the difference in weight determining the liquid density. Constant immersion hydrometers are typically more accurate for measuring specific gravity, while constant weight hydrometers can be more convenient for quick measurements.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element is constant. Each line corresponds to a specific energy transition within the atom, and the spacing between the lines is determined by the energy difference between the specific electronic states involved in the transition.
What is one factor that will be different between the experimental group in the control group?
The experimental group receives the treatment or intervention being studied, while the control group does not receive the treatment and is used for comparison. This is the primary difference between the two groups in an experiment.
What is the best definition of the enthalpy of a reaction?
The enthalpy of a reaction is the heat change that occurs during a chemical reaction at constant pressure. It represents the difference in energy between the products and reactants in the reaction.
What is the best definition of the enthalpy of reaction?
The enthalpy of reaction is the heat energy change that occurs in a chemical reaction at constant pressure. It is the difference between the sum of the enthalpies of the products and the sum of the enthalpies of the reactants.
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.
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.
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 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 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 is the difference between a control variable and a control treatment?
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.
What is the difference between ordinary prism and constant deviation prism?

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.
What is the difference between an experimental 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.
What is the difference between experimental 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.
What is the difference between feedback and control?
difference between feedback and control
Difference between attenuation constant and phase constant?
