A control group is what you are comparing your test agent against. For example, if you are testing to see if a new fuel works more efficiently that an existing one, you would test the existing fuel under the same conditions as the new fuel.
In a scientific study a sample must be run along with the test sample or samples to account for the normal BASELINE or BACKGROUND NOISE that results from an unaltered sample. This is "subtracted from each sample run in the test to account for unknown factors that may be falsely altering the test results.
For instance if you are testing various samples of tap water mixed with other chemicals to determine the calcium concentration, a "Control" (a.k.a. "Blank") is run with JUST tap water and no chemical added. Since tap water often has traces of calcium in it, the control will show how much of the readings are due to the calcium present in the tap water. This can then be subtracted from each other sample yielding useful data.
It means the part of the experiment that always stays the same, like if you are testing how tall plants grow in different temperatures, your control would be the type of plant...
a group that will not produce a reaction. it is to insure that the experiment is correct. Normally it is the one that contains water. Not a tested fluid like starch, bovine blood, or such.
A control group is the unaffected group in a science experiment.
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
The control group stays the same throughout the entire experiment.
The control is the group that doesnt get tested
A control group is must for every new experiment or uncommon experiment. Because when an experiment is being done anything unexpected could happen and to control the hazard a control group should be ready everytime. Otherwise it can be very dangerous for the experiment holders. to help you conclude that no uncontrolled factors significantly influenced your results
A control group is the unaffected group in a science experiment.
a control group assures that an experiment will be repeatable
The experimental group is use to compare with the control group, and viceversa. The experimental group is the group that we change the variable to experiment it's effects, as twcontrol group is the'original' experiment's results. Such a when we want to know the effect of changing a variable.
the group that does not change in the experiment VIVI :)
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
The control experiment allows a standard of comparison for the experimental group
control group
Control and Experiment group is what you would normally have in an experiment
what is the control group in basketball
a controlled experiment is an experiment that tests only one factor at a time by using a control group and experimental group
Every experiment requires a control group. This is so that the group that is manipulated can be compared to a group that has had nothing done to it., in order to measure changes.
