Truth. It’s natural to think that computability, range of application,and other things being equal, true theories are better than falseones, good approximations are better than bad ones, and highlyprobable theoretical claims are better than less probable ones. Oneway to decide whether a theory or a theoretical claim is true, closeto the truth, or acceptably probable is to derive predictions from itand use observational data to evaluate them. Hypothetico-Deductive(HD) confirmation theorists propose that observational evidence arguesfor the truth of theories whose deductive consequences it verifies,and against those whose consequences it falsifies (Popper 1959,32–34). But laws and theoretical generalization seldom if everentail observational predictions unless they are conjoined with one ormore auxiliary hypotheses taken from the theory they belong to. Whenthe prediction turns to be false, HD has trouble explaining which ofthe conjuncts is to blame. If a theory entails a true prediction, itwill continue to do so in conjunction with arbitrarily selectedirrelevant claims. HD has trouble explaining why the predictiondoesn’t confirm the irrelevancies along with the theory ofinterest.

Typical responses to this question maintain that the acceptability oftheoretical claims depends upon whether they are true (approximatelytrue, probable, or significantly more probable than their competitors)or whether they “save” observable phenomena. They then tryto explain how observational data argue for or against the possessionof one or more of these virtues.
When is it necessary for a scientists to do research
It does not get the independent variable.
What is an Experimental Group?
The group that get the independent variable to see how it
affects or changes
something or not.
What is a variable?
A variable is something that can
, either naturally or on purpose.
The factor that the scientist has changed (on purpose) in order to test the hypothesis .
only after a hypothesis is written C
Life Lessons Science is an ongoing process, as scientific investigations provide evidence that can either support or contradict a hypothesis.
A hypothesis can be replaced by a new or modified hypothesis after further investigation.
Thus, scientists are always prepared to modify their understandings of the natural world.
