How can a scientist test a hypothesis if he or she cannot do a controlled experiment?
scientists test their hypothesis buy making observations or doing research

What is the difference between a controlled experiment and a controlled group?
a controlled group is like an idea but an experiment that is controlled cannot be changed.
Why is it important for scientists to do repeated trials when doing an experiment?
Scientists, like everyone else, are imperfect. You cannot be absolutely sure that you have not made a mistake or overlooked something when you do an experiment, but if you do it several times and get the same result, then you can be more confident that you did it correctly. If you do it several times and get different results, that is a clue that tells you that there is something about the experiment that you have failed to understand.
Can a controlled variable be changed during an experiment?
No it cannot be changed in an expirement
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 a controlled varable?
Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.

What is a fingerprint patterns controlled variable?
A fingerprint pattern is not a controlled variable in a scientific experiment. Controlled variables are factors that are intentionally kept constant to ensure that the effects of the independent variable can be accurately measured. Fingerprint patterns are unique to individuals and cannot be controlled or manipulated in a controlled experiment.
Why a controlled experiment might be impossible?
A controlled experiment might be impossible if there are too many variables that cannot be controlled or if it is unethical or impractical to manipulate certain variables. Additionally, external factors outside of the researchers' control can also make it difficult to ensure a controlled environment for the experiment.
What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
How does a scientist explain something when a controlled experiment when a controlled experiment cannot be carried out?
'm not sure what your asking but I will attempt to explain what I believe you are saying... If event "x" happens and the data is recorded... By making assumptions based on facts that are known a person can conclude "y" hypothesis is the cause, however if no experiment can be done to test this or if the experiment cannot take into account extraneous and confounding variables, then the hypothesis is unable to be tested and remains an "educated guess"... There are ways around this however... Large diverse sample sizes eliminate the possibility that it is just some random occurrence brought by something else for example..
