Qualité des donnéesLa qualité des données, en informatique se réfère à la conformité des données aux usages prévus, dans les modes opératoires, les processus, les prises de décision, et la planification (J.M. Juran). De même, les données sont jugées de grande qualité si elles représentent correctement la réalité à laquelle elles se réfèrent. Ces deux points de vue peuvent souvent entrer en contradiction, y compris lorsqu'un même ensemble de données est utilisé avec un objectif commun.
Completeness (statistics)In statistics, completeness is a property of a statistic in relation to a parameterised model for a set of observed data. A complete statistic T is one for which any proposed distribution on the domain of T is predicted by one or more prior distributions on the model parameter space. In other words, the model space is 'rich enough' that every possible distribution of T can be explained by some prior distribution on the model parameter space. In contrast, a sufficient statistic T is one for which any two prior distributions will yield different distributions on T.
Jeu électroniqueAn electronic game is a game that uses electronics to create an interactive system with which a player can play. Video games are the most common form today, and for this reason the two terms are often used interchangeably. There are other common forms of electronic game including handheld electronic games, standalone systems (e.g. pinball, slot machines, or electro-mechanical arcade games), and exclusively non-visual products (e.g. audio games). Text-based game The earliest form of computer game to achieve any degree of mainstream use was the text-based Teletype game.
