A deductive approach usually begins with a hypothesis, whilst an inductive approach will usually use research questions to narrow the scope of the study. For deductive approaches the emphasis is generally on causality, whilst for inductive approaches the aim is usually focused on exploring new phenomena or looking at previously researched phenomena from a different perspective. Inductive approaches are generally associated with qualitative research, whilst deductive approaches are more commonly associated with quantitative research. However, there are no set rules and some qualitative studies may have a deductive orientation.
Three methods of reasoning are the deductive, inductive, and abductive approaches. Deductive reasoning moves from the general rule to the specific application: In deductive reasoning, if the original assertions are true, then the conclusion must also be true. For example, math is deductive: As a matter of fact, formal, symbolic logic uses a language that looks rather like the math equality above, complete with its own operators and syntax.
But a deductive syllogism think of it as a plain-English version of a math equality can be expressed in ordinary language: If entropy disorder in a system will increase unless energy is expended, And if my living room is a system, Then disorder will increase in my living room unless I clean it.
In the syllogism above, the first two statements, the propositions or premises, lead logically to the third statement, the conclusion.
Here is another example: A medical technology ought to be funded if it has been used successfully to treat patients. Adult stem cells are being used to treat patients successfully in more than sixty-five new therapies.
Adult stem cell research and technology should be funded. A conclusion is sound true or unsound falsedepending on the truth of the original premises for any premise may be true or false. At the same time, independent of the truth or falsity of the premises, the deductive inference itself the process of "connecting the dots" from premise to conclusion is either valid or invalid.
The inferential process can be valid even if the premise is false: There is no such thing as drought in the West. California is in the West. California need never make plans to deal with a drought.
In the example above, though the inferential process itself is valid, the conclusion is false because the premise, There is no such thing as drought in the West, is false. A syllogism yields a false conclusion if either of its propositions is false. A syllogism like this is particularly insidious because it looks so very logical—it is, in fact, logical.
But whether in error or malice, if either of the propositions above is wrong, then a policy decision based upon it California need never make plans to deal with a drought probably would fail to serve the public interest.
Assuming the propositions are sound, the rather stern logic of deductive reasoning can give you absolutely certain conclusions. However, deductive reasoning cannot really increase human knowledge it is nonampliative because the conclusions yielded by deductive reasoning are tautologies-statements that are contained within the premises and virtually self-evident.
Therefore, while with deductive reasoning we can make observations and expand implications, we cannot make predictions about future or otherwise non-observed phenomena.
You could say that inductive reasoning moves from the specific to the general. Much scientific research is carried out by the inductive method: Conclusions reached by the inductive method are not logical necessities; no amount of inductive evidence guarantees the conclusion.
This is because there is no way to know that all the possible evidence has been gathered, and that there exists no further bit of unobserved evidence that might invalidate my hypothesis.
Thus, while the newspapers might report the conclusions of scientific research as absolutes, scientific literature itself uses more cautious language, the language of inductively reached, probable conclusions: What we have seen is the ability of these cells to feed the blood vessels of tumors and to heal the blood vessels surrounding wounds.
The findings suggest that these adult stem cells may be an ideal source of cells for clinical therapy.
For example, we can envision the use of these stem cells for therapies against cancer tumors [ Rather, they are cogent: Nor are inductive arguments simply false; rather, they are not cogent. It is an important difference from deductive reasoning that, while inductive reasoning cannot yield an absolutely certain conclusion, it can actually increase human knowledge it is ampliative.Defining a research problem is the fuel that drives the scientific process, and is the foundation of any research method and experimental design, from true experiment to case study.
Inductive approach, also known in inductive reasoning, starts with the observations and theories are proposed towards the end of the research process as a result of observations. INTRODUCTION.
A research design is the framework or guide used for the planning, implementation, and analysis of a study ().It is the plan for answering the research question or hypothesis. Research Onion- Layers Executing Successful Methods of Accomplishing Research Results.
Summary– There is set of procedures designed through which one can get into the core of the research are produce attheheels.comch onion helps in systematic study of the methods involved in executing a research . Inductive and deductive reasoning are often confused.
This lesson introduces the concept of reasoning and gives you tips and tricks to keeping inductive and deductive reasoning straight. Deductive research is quite different from inductive research as it uses a top-down approach in opposition to the inductive research.
Deductive research can be understood as a research category that includes a process of testing hypothesis in order to verify a theory.
