How can a scientist do a controlled experiment if it is not possible to use several different groups?

Not every experiment has control groups. If control groups are not feasible, you do what you can, and you may still learn something of interest. In the case of something like medical research, which really should have control groups, you can still use general statistical information to establish a baseline. People (for example) normally grow to a certain average height. We administer experimental drug X to our subjects, and they grow to a certain height which can be compared to the statistical average. This does tell us something.

Which of the following describes the possible pricing pattern of firms in perfect competition?
each firm charges a different price to allow for difference fixed cost
What is sample space?
set of all possible result of an experiment or trial is known as sample space and it is denoted by capital s (S). For example Throwing dies we get the sample space of {1,2,3,4,5,6} Tossing a coin we get the sample space, S={H,T}, here H-head and T-tail.
How does globalization affect the Philippines economy?
This makes it possible to sell goods in many different areas. They have more trade options and even more options for jobs.
Under what market conditions is monopolistic competition possible?
a large number of sellers produce a product or service that is perceived by consumers as being different from that of a competitor but is actually quite similar

What are two types of scientific investigations that scientist use when a controlled experiment is not practical?
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
How do scientist?
He or she states the problemThe scientist forms a hypothesis, a possible solution to the problem. The simplest solution is often the best solution.Next, a scientist might want to perform a controlled experiment. A controlled experiment can give a scientist more information about his or hers hypothesis.Results are recorded and analyzed.Using the data the scientist can develop a conclusion.
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.

No it will not be all ways possible.
How bad scientist carry out their experiment?
As Bad , As Possible !! :P
