False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.

What is the control in an expiriment?
The control is the subject in an experiment not introduced to the dependent variable. For instance if you were to test the effect of different types of fertilizer on plants, the control would be the plant with no fertilizer.
Definitions of the 3 types of variables in doing an experiment?
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
What does controlled experiment mean in science terms?
All science experiments are performed in a controlled manner which means, there will be a positive control, a negative control and importantly the subject sample(s) who's behavior is not known. The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.Any fault or irregularities of the controls will destroy the authenticity of an experiment.
What is the subject in an experiment?
It is the thing you conduct your experiment on.
Factor in a scientific experiment that is subject to change?
A factor in a scientific experiment that is subject to change is called a variable.
In a experiment?
A control in an experiment is the subject not exposed to the independent variable, thereby determining whether the independent variable is the true cause of the results.

The group in an experiment that is not exposed to the tested variable is called the group?
An unexposed subject is the "control" for the experiment. The purpose is to establish an idea of what would normally occur outside the testing procedure. Similarly, in human tests, an inactive "placebo" is given to some subjects to verify that the changes occur independently of the psychosomatic (belief-driven) effects. In a "double blind' experiment, the person distributing the medication also does not know whether any particular individual is receiving the actual drug or a placebo. This is hidden in coded form until the results are recorded.
In an experiment a group that receives no treatment is called what?
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.

The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.Any fault or irregularities of the controls will destroy the authenticity of an experiment.
Is there one dependent variable in an experiment?
No, there can be several outputs that are dependent variables. For example, you will have a number of grades in different subjects when you finish school. So the experiment (your schooling) will result in a number of dependent variables. Similarly, the school's outcome for its "experiment" of teaching a number of pupils will be several sets exam grades: a different dependent variable for each subject.
Why is a controlled experiment better than a non controlled experiment?
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
The experimental procedure in which both the experimenter and subject are unaware of who is in the experimental and who is in the control group is referred to as the?
Double blind experiment.
What is the name of the effect where the subject of an experiment alters behavior just because he is the subject of the experiment?
Subject bias is a term that can be used to describe a subject's manipulation of an experiment.
What is the subject in an experiment?
It is the thing you conduct your experiment on.
What is the purpose of a control in an experiment?
The experimental control provides a base-line result or set of results, from which you can compare the variables' effects against. It's designed to minimize the effects of variables (other than the single independent variable). Control groups are often included in medical or psychological experiments so that the results of an experiment are considered reliable and trustworthy.Example:A mystery-drug cure is being tested. One group of patients is given the drug and the other group is not. The group without the drug will be subject to all the same conditions that the other group are under, thereby seeking to eliminate any unforeseen effecting environmental factors. This makes it possible to compare, and therefore measure, the impact any drug would have.
