Dependent and independent variable
Variables
have no variables
Controlled experiments contain two parts, the control group and the variable group. The variable group is the group that receives treatment and attention. These two groups are used to compare to each other at the end of the experiment.
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
experiment
The two groups in a controlled experiment are the experimental group, which receives the treatment being tested, and the control group, which does not receive the treatment and serves as a baseline for comparison.

experiment
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.

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.
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.
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
