===[[AP_Statistics_Curriculum_2007_IntroTools |Statistics with
Tools (Calculators and Computers)]]=== All methods for data
analysis, understanding or visualizing are based on models that
often have compact analytical representations (e.g., formulas,
symbolic equations, etc.) Models are used to study processes
theoretically. Empirical validations of the utility of models
are achieved by inputting data and executing tests of the
models. This validation step may be done manually, by computing
the model prediction or model inference from recorded
measurements. This process may be possibly done by hand, but
only for small numbers of observations (<10). In practice, we
write (or use existent) algorithms and computer programs that
automate these calculations for All methods
