For example, weather forecasting is an area where deductive reasoning probabilities are often used. A meteorologist will look at the data, and using their skill and judgment, decide upon the likely weather for that day. They are aware that a certain pattern of initial conditions frequently leads to a certain weather type. However, they will never say that it is definitely going to rain, because the weather is too unpredictable, and they can never be sure that their initial assumptions are correct.
Michael Fish, the respected British meteorologist, categorically stated in that there was no chance of a hurricane hitting Southern England. He was wrong, and the unprepared country was devastated. The initial premises of his deductive reasoning were wrong. These days forecasters always warn of adverse weather as a percentage chance, affording people the choice of preparing for the worst.

The fact that there are some people who eat carrots but are not quarterbacks proves the flaw of the argument. In this example, the first statement uses categorical reasoning , saying that all carrot-eaters are definitely quarterbacks. This theory of deductive reasoning — also known as term logic — was developed by Aristotle , but was superseded by propositional sentential logic and predicate logic.
Deductive reasoning can be contrasted with inductive reasoning , in regards to validity and soundness. Aristotle started documenting deductive reasoning in the 4th century BC.

Application of Deductive Approach (Deductive Reasoning) in Business Research. In studies with deductive approach, the researcher formulates a set of hypotheses at the start of the research. Then, relevant research methods are chosen and applied to test the hypotheses to prove them right or wrong.
In logic, we often refer to the two broad methods of reasoning as the deductive and inductive approaches. Deductive reasoning works from the more general to the more specific. Sometimes this is informally called a "top-down" approach. We might begin with thinking up a theory about our topic of interest.
The main difference between inductive and deductive approaches to research is that whilst a deductive approach is aimed and testing theory, an inductive approach is concerned with the generation of new theory emerging from the data. Reasoning methods and Argumentation The main division between forms of reasoning that is made in philosophy is between deductive reasoning and inductive reasoning. Formal logic has been described as 'the science of deduction'. The study of inductive reasoning is generally carried out within the field known as informal logic or critical thinking.
Deductive research aims to test an existing theory while inductive research aims to generate new theories from observed data. Deductive research works from the more general to the more specific, and inductive research works from more specific observations to more general theories. Inductive and Deductive Research Approaches 5 and quantitative with exploratory and confirmatory to more clearly reflect the relationship between the two methodologies. The methods may be different but the goals remain the same.
