Is there ever a good reason when it would be appropriate to perform an experiment without a control group?

Yes only when the experiment is obvious, for example, if I wanted to see what drink would be healthier for your body water or juice it is obvious that water is healthier because it contains no chemicals

What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is a experiment without a variable?
An experiment has to have a varible, if it doesn't that it's probably and engineering experiment or robotics. I think its called a "control"
Why is a control group important to a controlled experiment?
Because without it, it wouldn't be organized.
Why is a control group necessary in the scientific experiment?
Without the control group, the test is not able to measure the difference with a standard condition
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.

What are control factors?
A control factor is one of the varriables that can be controlled in a science experiment. It is left as a constant without being changed.
Why is control setup necessary in an experiment?
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?
Why a control needed in a valid experiment?
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
Why is a control group important to a controlled experiment?
Because without it, it wouldn't be organized.
It is safe to perform a lab experiment without goggles when?
NO! If you dont wear goggles that experiment may go horibly wrong NOMATTER WHAT ALWAYS WEAR goggles
Can control in an experiment be changed?
no the control is that which is used to test your hypothesis. if mentos would blow up if you use caffeine and you used water, coke, and milk the water would be the control without it you cant do an experiment.
What do control setup and experimental setup have in common?
Everything except what you're measuring. EXAMPLE: In a biological experiment using specially treated cells the experiment is run with the cells; this is the experiment. Then the experiment is run again with the same cells WITHOUT the special treatment; this is the control.
Why is a control group necessary in the scientific experiment?
Without the control group, the test is not able to measure the difference with a standard condition
Why is a control group important to have in a experiment?
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
What is a purpose of a control?
The purpose of a control in any experiment is so that you have a natural example to look at at. Ex: If I was doing an experiment on fertilizer, I'd have three different fertilizers and a plant without fertilizer so I could see how it would grow without fertilizer so I could backtrack if need be.
