While hypotheses frame explanatory studies and provide guidance for measurement and statistical tests, deductive, exploratory research does not have a framing device like the hypothesis. To this purpose, this article examines the landscape of deductive, exploratory research and offers the working hypothesis as a flexible, useful framework that can guide and bring coherence across the steps in the research process.
Note: Philosophers including Prof. Fisher distinguish induction generalizing the traits of some sample to other things from abduction inference to the best explanation , whereas the content below blurs both of these together under the single heading of "induction". When taking this class with Professor Fisher, it's better to rely upon his notes or slides on this topic, rather than the content below. Induction is a process of trying to figure out the workings of some phenomenon by studying a sample of it. You work with a sample because looking at every component of the phenomenon is not feasible. Induction is a creative process. The scientist must carefully study a sample of a phenomenon, then formulate a hypothesis to explain the phenomenon.
States that there are two general approaches to reasoning which may result in the acquisition of new knowledge: inductive reasoning commences with observation of specific instances, and seeks to establish generalisations; deductive reasoning commences with generalisations, and seeks to see if these generalisations apply to specific instances. Most often, qualitative research follows an inductive process. In most instances, however, theory developed from qualitative investigation is untested theory. Both quantitative and qualitative researchers demonstrate deductive and inductive processes in their research, but fail to recognise these processes. This is not incompatible with the use of qualitative research methods. Argues that the adoption of formal deductive procedures can represent an important step for assuring conviction in qualitative research findings.
A feature of research designs are the approach to reasoning that they incorporate. There are various approaches that can be taken. Three of the main ways are deduction, induction and abduction. You can do deductive reasoning while sitting in your armchair. Deductive reasoning involves inferring that if propositions A and B are both true, then this implies that C is also true. The classic example is over two thousand years old and involves the question of whether the ancient Greek philosopher Socrates was mortal.
The potential of working hypotheses for deductive exploratory research
Theory structures and informs social work research. Conversely, social work research structures and informs theory. Students become aware of the reciprocal relationship between theory and research when they consider the relationships between the two in inductive and deductive approaches. In both cases, theory is crucial but the relationship between theory and research differs for each approach. Inductive and deductive approaches to research are quite different, but they can also be complementary.
If you're conducting research on a topic, you'll use various strategies and methods to gather information and come to a conclusion. So what's the difference between inductive and deductive reasoning, when should you use each method, and is one better than the other? We'll answer those questions and give you some examples of both types of reasoning in this article. When you're using inductive reasoning to conduct research, you're basing your conclusions off your observations. You gather information - from talking to people, reading old newspapers, observing people, animals, or objects in their natural habitat, and so on. Inductive reasoning helps you take these observations and form them into a theory. You can think of this process as a reverse funnel — starting with more specifics and getting broader as you reach your conclusions theory.
Inductive and deductive approaches to research
Theories structure and inform sociological research. So, too, does research structure and inform theory. The reciprocal relationship between theory and research often becomes evident to students new to these topics when they consider the relationships between theory and research in inductive and deductive approaches to research. In both cases, theory is crucial.
Inductive vs. deductive reasoning
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. 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. One specific inductive approach that is frequently referred to in research literature is grounded theory, pioneered by Glaser and Strauss.
Inductive reasoning is a method of reasoning in which the premises are viewed as supplying some evidence, but not full assurance, of the truth of the conclusion. Inductive reasoning is distinct from deductive reasoning. While, if the premises are correct, the conclusion of a deductive argument is certain , the truth of the conclusion of an inductive argument is probable , based upon the evidence given. The three principal types of inductive reasoning are generalization , analogy , and causal inference. Each of these, while similar, has a different form.
Deductive Approaches and Some Examples
Published on April 18, by Raimo Streefkerk. Revised on November 11, The main difference between inductive and deductive reasoning is that inductive reasoning aims at developing a theory while deductive reasoning aims at testing an existing theory. Inductive reasoning moves from specific observations to broad generalizations, and deductive reasoning the other way around.
