Psycho is slang for a person who is psychotic or psychopathic. The term is often considered offensive or derogatory. However, when used within compound terms such as 'psychology' or 'psychotherapy', the word refers neutrally to the psyche (mind or soul).
Psycho may also refer to:
Paranoia [ˌpærəˈnɔɪ.ə] (adjective: paranoid [ˈpærə.nɔɪd]) is a thought process believed to be heavily influenced by anxiety or fear, often to the point of irrationality and delusion. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracy concerning a perceived threat towards oneself. (e.g. "Everyone is out to get me.") Making false accusations and the general distrust of others also frequently accompany paranoia. For example, an incident most people would view as an accident or coincidence, a paranoid person might believe was intentional. However, just because an individual is paranoid does not necessarily mean his or her suspicions are false, as noted in Catch-22: "Just because you're paranoid doesn't mean they aren't after you."
Historically, this characterization was used to describe any delusional state. In modern colloquial use, the term "paranoia" is sometimes misused to describe a phobia. The general lack of blame in phobia disorders sharply differentiates the two. In other words, fearing that something bad or harmful might happen does not in itself imply paranoia. Rather, with paranoia there is an irrational fear of malice by others (excepting rare cases of schizophrenia).
Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.
