14.4 Statistical Methods

Statistical method is the systematic method which is used to organize, present, analyse and
interpret the large or small volume of numerical information effectively. It is nothing but the
method by which statistical data are analysed.

Statistical method ranges from the most elementary descriptive devices which may be understood
by the common man to those complicated mathematical procedure which can be apprehended
only by the expert theoreticians.

analysis and interpretation of numerical data”, however what they missed in their definition is
the organization of data. Thus statistical method is the “science of collection, organization,
presentation, analysis and interpretation of numerical data” and for a statistical method above
five stages are essential and comprehensive.
