Problem detection.

Breaking down data.

Conclusion based on symptoms.

Diagnosis is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines, with variations in the use of logic, analytics, and experience, to determine "cause and effect".

Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.The word comes from the Ancient Greek ἀνάλυσις (analysis, "a breaking-up" or "an untying;" from ana- "up, throughout" and lysis "a loosening").

The act or process of identifying or determining the nature and cause of a disease or injury through evaluation of patient history, examination, and review of laboratory data.

Detailed examination of the elements or structure of something

The opinion derived from such an evaluation.

Short for psychoanalysis

A critical analysis of the nature of something.

The separation of an intellectual or material whole into its constituent parts for individual study.

The conclusion reached by such analysis.

The study of such constituent parts and their interrelationships in making up a whole.

(Biology) A brief description of the distinguishing characteristics of an organism, as for taxonomic classification.

A spoken or written presentation of such study

(medicine) The identification of the nature and cause of an illness.

The separation of a substance into its constituent elements to determine either their nature (qualitative analysis) or their proportions (quantitative analysis).

The identification of the nature and cause of something (of any nature).

The stated findings of such a separation or determination.

(taxonomy) A written description of a species or other taxon serving to distinguish that species from all others; especially a description written and published in Latin.

A branch of mathematics principally involving differential and integral calculus, sequences, and series and concerned with limits and convergence.

Synonym of diagnose

The method of proof in which a known truth is sought as a consequence of a series of deductions from that which is the thing to be proved.

The art or act of recognizing the presence of disease from its signs or symptoms, and deciding as to its character; also, the decision arrived at.

(Linguistics) The use of function words such as prepositions, pronouns, or auxiliary verbs instead of inflectional endings to express a grammatical relationship; for example, the cover of the dictionary instead of the dictionary's cover.

Hence, the act or process of identifying the nature or cause of some phenomenon, especially the abnormal behavior of an animal or artifactual device; as, diagnosis of a vibration in an automobile; diagnosis of the failure of a sales campaign; diagnosis of a computer malfunction.

Psychoanalysis.

Scientific determination of any kind; the concise description of characterization of a species.

Systems analysis.

Critical perception or scrutiny; judgment based on such scrutiny; esp., perception of, or judgment concerning, motives and character.

(countable) Decomposition into components in order to study (a complex thing, concept, theory etc.).

Identifying the nature or cause of some phenomenon

(countable) The result of such a process.

The mathematical study of functions, sequences, series, limits, derivatives and integrals.

Proof by deduction from known truths.

The process of breaking down a substance into its constituent parts, or the result of this process.

The analytical study of melodies, harmonies, sequences, repetitions, variations, quotations, juxtapositions, and surprises.

Psychoanalysis.

A resolution of anything, whether an object of the senses or of the intellect, into its constituent or original elements; an examination of the component parts of a subject, each separately, as the words which compose a sentence, the tones of a tune, or the simple propositions which enter into an argument. It is opposed to synthesis.

The separation of a compound substance, by chemical processes, into its constituents, with a view to ascertain either (a) what elements it contains, or (b) how much of each element is present. The former is called qualitative, and the latter quantitative analysis.

The tracing of things to their source, and the resolving of knowledge into its original principles.

The resolving of problems by reducing the conditions that are in them to equations.

A syllabus, or table of the principal heads of a discourse, disposed in their natural order.

The process of ascertaining the name of a species, or its place in a system of classification, by means of an analytical table or key.

An investigation of the component parts of a whole and their relations in making up the whole

The abstract separation of a whole into its constituent parts in order to study the parts and their relations

A form of literary criticism in which the structure of a piece of writing is analyzed

The use of closed-class words instead of inflections: e.g., `the father of the bride' instead of `the bride's father'

A branch of mathematics involving calculus and the theory of limits; sequences and series and integration and differentiation

A set of techniques for exploring underlying motives and a method of treating various mental disorders; based on the theories of Sigmund Freud;

While primarily used in medicine, diagnosis also applies to technical issues and problem detection.

Techniques include data collection, deconstructing information, and logical interpretation.

Analysis breaks down and examines the components of an issue or concept for better understanding.

Diagnosis identifies and labels a specific problem, often in medical contexts.

Analysis is exploratory and focuses on understanding, while diagnosis is decisive, aiming to pinpoint specific issues.

Analysis is common in fields like economics, science, literature, and engineering.

A test used to identify the presence of a particular issue or condition.

Diagnosis often involves some form of analysis to interpret symptoms or patterns.

Medical tests, technical tools, and symptom assessments are common.

Yes, analysis can yield various hypotheses or insights due to its exploratory nature.

Yes, diagnosis often requires expertise in the relevant field.

Yes, many analysis processes, like statistical analysis, can be automated with software tools.

Yes, analysis in literature involves breaking down themes, characters, and structure.

Diagnosis typically results in a clear conclusion about the problem.

Diagnosis aims for high accuracy due to its clear labeling, while analysis may involve more speculation.
