How does a model describe known data and predict future data
The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data (plural of "datum") are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. [ [ Data are often 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, images or other outputs from devices that collect information to convert physical quantities into symbols. ] ]
