A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
risk control is when cows are born in the ocean risk control is when cows are born in the ocean
experimental and control groups
a process of systematically selecting representation elements of a population
Keeping something harmful under control
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.

A 'control' is a sample with a known outcome. By testing the control at the same time, with the same operator, under the same conditions as the 'test sample' one builds validity into the test result, assuming of course, that the result gives the expected outcome.
The full set of data from which a subset (sample) is taken.

Again another of my homework questions and i think its control
You're not meant to have foreign organisms inside your body (excluding the gut which technically isn't inside your body). So if you're sick and the organism can be isolated and cultured from a sample you gave from the area that is affected (eg a sputum sample if you have a chest infection, a blood sample if you have septacaemia), it has to be the cause of the disease. A control sample is always given to exlude the possibility of contamintation.
it is need so as a control.

awesome
Water is often used as a control sample because it is a neutral substance that does not interfere with the experiment. By comparing the results from the experimental samples to the control sample of water, researchers can more accurately determine the effects of the variables being tested. Additionally, water is readily available, inexpensive, and easily controlled for consistency.
Suppose you took a sample of someone's blood in a tube then noticed a crack in the tube. You would be doubtful of the integrity of the sample because the crack might harbour contaminants that would cast doubt on measurements.
