Deduction logic uses a hypothesis and examines the possibilities in order to reach a logical conclusion and inductive reasoning makes wide sweeping generalizations from a set of specific observations. The scientific method requires deductive logic to test a hypothesis and scientists also use inductive reasoning to form hypotheses.Know More
Deductive logic, also known as the "from the top down" approach, starts with a general idea and works down to the details. A hypothesis is generally formed using a syllogism, or a three-stepped argument. For example:
Because of the broad generalizations used in inductive logic, there is a reasonable chance that this leap-of-faith assumption is wrong. An example of inductive logic is "Elizabeth is a woman and has long hair, therefore all women have long hair." While the conclusion is false, it allows scientists to form theories and hypotheses to test.
Deduction can give absolute proof to a theory as long as the premises are correct, however if the premises remain unproven, they must be accepted at face value. Inductive logic may be driven by observations and measurements, it never offers proof of a theory. The scientific method uses a mixture of deductive and inductive reasoning to work.Learn more about Logic & Reasoning
A deductive, or "top-down," approach to research methodology begins with hypotheses based on existing knowledge or literature. In other words, it seeks to test an established theory.Full Answer >
Logic proof solvers, or logic calculators, are tools that help individuals check the validity of their premises and conclusions. Logic proofs are a numbered series of letters and symbols that symbolically represent an argument.Full Answer >
Formal logic deals with apprehension, judgment and reasoning while material logic deals with the evaluation of measurable factors. These two divisions of logic are not considered strictly separate and there is some debate over whether or not they are different in a purely legal sense.Full Answer >
In logic, "false cause and effect" is when one event is said to have caused another event just because the first event preceded the second event. It is a logical fallacy because it uses sequence as the only evidence without considering other factors.Full Answer >
