What is the contolled and experimental group in an experiment?
Experimental control is a group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment It is also the standard of comparison. -Also, look for the following things: Experimenter Bias, History, Maturation, Instrumentation, Selection, Order, and Statistical regression. All of these should be questioned.
Why do you need to have a control group when conducting experiments?
The control group gives you something to compare the results to.
Do all experiments need to have a control group?
yes all experiments need to have a control
What is a control and control group?
In science, a "control group" is a group of test subjects that do not receive any of the experimental food/ gas/ poison/ bizarre additions to their environment, etc., that theother groups in the test do get.)For example, if you wanted to see the effects of feeding plutonium to hamsters,(not recommended by the way)you would get two groups of hamsters. One group is fed the plutonium, and all effectswould be observed. (none would be good)What you need to show what happens to ordinary hamsters over the same period of timeis called a "control group".This would be a (luckier) group of hamsters that were not fed the plutonium.Then you could show the differences (considerable) of the resultant effects on the two groups.
What is the control group in an experiment?
set up the same way as the experimetal group except the independent variable is absentA control group is identical to the experimental group in every way but it lack the experimental variable. This is the group not being tested on.A control group is a group of specimens on which you do not perform the experiment procedure. The control group therefore tells you how the specimen behaves under "normal" circumstances, and you can compare your other specimens to this control group to study the effects of the experiment.When someone performs an experiment on biological organisms they do something to the organism. Then they need to know if what they did changed the organism in a way that would not have happened had they not performed the experiment. So, they need to compare the group they did something to with a group that nothing was done to. This comparison group that had nothing done to it is called a control group.The control group in an experiment is the group that stays the same and is not changed in any way. Because it is not changed, other variables may be compared to it.For example:You are testing whether temperature has an effect on the breaking point of rubber bands. You take one rubber band and put it in the freezer and another is heated. A third rubber band is left at room temperature. The one left at room temperature is the control. It is the normal result you are comparing your other two results to.You must be sure that the rubber bands are exactly the same in size, width, construction and composition.Controlled experiment means you keep every other variable constant, except for one ( the one being tested). A variable means something that varies, or keep changing. Controlled experiment removes all the possibilities of external influences on the subject. Everything else must remain constant in a controlled experiment, that's how you will able to study it in its true context.To help researchers conclude that results arerelated to the new drug and not to the orange juiceIs the normal/known setting or amount or value that is tested against. That way you can determine change from experiment.
Why do you need a a control group?
You need a control group to compare your experimental group to something.
What are the two groups you need to have an experiment?
You need a control group and an experimental group.
Why do you need a control group and a experimental group?
A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied. The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.
What does controls mean in a science project?
Control in a science experiment means it stays the same and you don't do anything to it.
Why must controls be used in fertilizer experiment?
to elliminate soures of error
Why is there a control specimen?
A control specimen is used to provide a baseline for comparison in an experiment. It allows researchers to assess how the experimental group reacts in comparison to a standard or neutral condition. Control specimens help ensure that any changes observed are due to the experimental treatment and not other factors.
What is control groups?
A control group is used as a base line for comparison to experimental results.

What is control variable?
what is an controlled variable. we need to know it for our science proformance asscement!!! From a friend in need!
