Control
How can scientist test a hypothesis if it is not possible to do a controlled experiment?
If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.
What is controlled in a controlled study?
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
Are controls always necessary in an experiment?
Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
Why is a controlled experiment valuabl e to a scientist?
It gives the scientist something to compare their results to.
How did your observed results compare to your expected results?
The observed results were in line with the expected results, indicating that the hypothesis was supported. This suggests that the experiment was conducted correctly and the variables were controlled effectively.
What results stay the same in an experiment?
controlled results stay the same in an experiment
The importance of a control in an experiment?
When doing a controlled experiment, you get accurate results.

Scientists may do a controlled experiment to?
Communicate results
How does a controlled experiment?
It works when repeated to get results that are the same
How is a control useful in a scientific experiment?
A control experiment provides a benchmark against which to compare the results of the main experiment. For example, to know if heating a material changes its resistance, you must be able to compare the results of the heated experiment to a copy in which the material was left unheated.
