because your adopted. nawh just kidding, but seriously one reason why a controlled experiment may not be possible is because...ok lets say you had an experiment of a cancer-causing chemical, they might exclude volunteers who have other serious health problems. by exerting great care in planning these kinds of investigations, scientists can discover reliable patters that add to scientific knowledge.

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.
After you reach a conclusion about an experiment you may find you need to experiment more?
Yes, that is possible. It's to be expected.
After you reach a conclusion about an experiment you may find you need to experiment more.?
It is certainly possible. The conclusion from your experiment may prove to be tentative and you may need to design a better experiment to improve the reliability of the conclusion, or the experiment may suggest alternatives which you may wish to explore. Most of science is about that: an experiment leads to conclusions. Further experiments result in refinements to the conclusions and, occasionally, to the replacement of earlier theories with new models.
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.
How many independent variable are there in a controlled experiment?
In a controlled experiment, there is typically one independent variable. This is the variable that researchers manipulate to observe its effect on the dependent variable. Keeping all other variables constant allows for a clear understanding of the relationship between the independent and dependent variables. However, some experiments may include multiple independent variables, but each one must be tested in a controlled manner.
Scientists may do a controlled experiment to?
Communicate results

During an experiment which factors may be controlled so that researchers can draw a logical conclusion fron the experiment?

Can everything be studied by setting up a controlled experiment?
No, not everything can be studied through controlled experiments. Some phenomena, such as historical events or natural disasters, may not be ethical or possible to replicate in a controlled setting. In such cases, researchers may use observational studies, simulations, or other methods to study these phenomena.
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
After you reach a conclusion about an experiment you may find you need to experiment more?
Yes, that is possible. It's to be expected.
A factor in a experiment that can change?
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
What is the independent variable in an experiment?
Independent variable is what you, the experimenter, change or enacts in order to do your experiment

What are the two types of variables in an experiment?
The two types of variables in an experiment are independent variables, which are controlled by the experimenter and can be manipulated, and dependent variables, which are the outcome or response that is measured in the experiment and may change in response to the independent variable.
What is the term for the factor being measured in an experiment?
The term for the factor being measured in an experiment is the "dependent variable." This is the variable that may change in response to manipulations of the independent variable, which is the variable that is being controlled or manipulated by the researcher.
Why don't hot water run into washer?
Probably because you have a plugged inlet filter. All washers have this tiny filter inside the inlet hose. -Another possible reason is the electrically controlled inlet valve, it may fail .
