statistics

concept

Statistics is a discipline whose
objective is the interpretation of
numerical data sets that are
extracted from empirical facts,
dealing with gathering, organizing
and analyzing numerical data with
the purpose of drawing
conclusions and making decisions
with what is said in the analysis.

descriptive

can be defined as a method to
numerically describe numerous
sets. Because it is a numerical
description method, it uses the
number as a means to describe a
set, which must be numerous,
since statistical permanences do
not occur in rare cases. It is not
possible to draw concrete and
precise conclusions from the
statistical data. (Vargas, p.33)

inferential

it studies the probability of success
of the different possible solutions
to a problem in the different
sciences in which it is applied and
for this it uses the data observed in
one or several samples of the
population. By creating a
mathematical model, it infers the
behavior of the total population
based on the results obtained in
the observations of the samples.
