STATISTICAL INFERENCE [1 record]

Record 1 2004-09-21

English

Subject field(s)
  • Statistics
DEF

... a form of reasoning from sample data to population parameters; that is any generalization, prediction, estimate, or decision based on a sample.

OBS

... in the past (and to some extent in the present), it was fashionable to divide the subject matter of statistics into two distinct subjects called descriptive statistics and statistical inference. In the former, the main emphasis is placed on arithmetic and graphical distillation of data to help describe the existing situation. Statistical inference, on the other hand, involves considerably more sophisticated notions concerned with general decision making and prediction. Not only is the mathematics involved often more difficult, but, as an example of an inductive science (inducting from the particular to the general), it contains subtleties and nuances that are not always revealed by a mathematical formula.
