Deductive Approach (Deductive Reasoning)

A deductive approach is concerned with “developing a hypothesis (or hypotheses) based on existing theory, and then designing a research strategy to test the hypothesis”[1] It has been stated that “deductive means reasoning from the particular to the general. If a causal relationship or link seems to be implied by a particular theory or case example, it might be true in many cases. A deductive design might test to see if this relationship or link did obtain on more general circumstances”[2]. Deductive approach can be explained by the means of hypotheses, which can be derived from the propositions of the theory. In other words, deductive approach is concerned with deducting conclusions from premises or propositions. Deduction begins with an expected pattern “that is tested against observations, whereas induction begins with observations and seeks to find a pattern within them”[3]. Advantages of Deductive Approach Deductive approach offers the following advantages: Possibility to explain causal relationships between concepts and variables Possibility to measure concepts quantitatively Possibility to generalize research findings to a certain extent Alternative to deductive approach is inductive approach. The table below guides the choice of specific approach depending on circumstances:   Deductive approach preferred Inductive approach preferred Wealth of literature Abundance of sources Scarcity of sources Time availability Short time available to complete the study There is no shortage of time to compete the study Risk To avoid risk Risk is accepted, no theory may emerge at all Choice between deductive and inductive approaches Deductive research approach explores a known theory or phenomenon and tests if that theory is valid in given circumstances. It has been noted that “the deductive approach follows the path of logic most closely. The reasoning starts with a theory and leads to a new hypothesis. This hypothesis is put to the test by confronting it with … Continue reading Deductive Approach (Deductive Reasoning)
