Want this question answered?
The control group.
ummm 'cause u need a controlled experiment so the answer is correct and more accurate. People can get different answers and that's experimental value but a scientist need's the answer to be true value. I'm in 6th grade and this is 4 science. (: :P =D
different kind experiment data present bar graph
all it is is the uncontrolled experiment is a little bit different
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.

experimental and control
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
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.
There are a number of different things which can improve the estimate:select an appropriate estimation method,repeat the experiment more times,Improve the accuracy of your measurement,ensure that other variables are properly controlled.
The control group does not change, while the experimental group is the variable you are changing.

The theoretical model does not accurately reflect the experiment.
