Hypothesis vs. Theory — Is There a Difference?

Difference Between Hypothesis and Theory

Hypothesisnoun

A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.

Theorynoun

A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

Hypothesisnoun

Something taken to be true for the purpose of argument or investigation; an assumption.

Theorynoun

The branch of a science or art consisting of its explanatory statements, accepted principles, and methods of analysis, as opposed to practice

a fine musician who had never studied theory.

Hypothesisnoun

The antecedent of a conditional statement.

Theorynoun

A set of theorems that constitute a systematic view of a branch of mathematics.

Hypothesisnoun

(sciences) Used loosely, a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation. As a scientific term of art, see the attached quotation. Compare to theory, and quotation given there.

Theorynoun

Abstract reasoning; speculation

a decision based on experience rather than theory.

Hypothesisnoun

(general) An assumption taken to be true for the purpose of argument or investigation.

Theorynoun

Theorynoun

(obsolete) Mental conception; reflection, consideration.

Hypothesisnoun

a tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena;

Theorynoun

(sciences) A coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed, or which sets out the laws and principles of something known or observed; a hypothesis confirmed by observation, experiment etc.

Hypothesisnoun

A theory is consistent if it has a model.

Theorynoun

a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena;
