Characteristics of Statistics

Statistics are Aggregate of Facts

An individual isolated number cannot be real called as Statistics. Statistics deal among groups,
although not individual things. In favor of examples, one crash, one childbirth, one destruction,
or, etc. cannot be named as Statistics. However, the collective of figures relating to crashes,
childbirth, deaths, etc. over different periods otherwise areas can be named Statistics.

Statistics Express Numerically

Statistics are just the numerical arguments of facts. So, the argument shown in numbers of
decreased in order to numbers can be rated as Statistics. For instance, ages of 4 person might
be said as "teenage,", "middle age" and "aged"; they are never distrust, statements for facts,
although will not be named Statistics, since they are not numerically expressed. However, if
these declarations of facts are expressed in numerical measurements, say 12-years, 25-years
and 56-years, after that they will be named Statistics of ages.

Statistics are Numerated or Approximated according to Sensible Standard of
Accuracy

A fairly good standard of exactness is essential in both counting and estimation because, over
there cannot be a regular standard of exactness for altogether sorts of studies. For instance, in
measuring of weight, a fractional part of a gram can be neglected. But then, in measuring nasal
bone length, you can't ignore fractional part of an inch.

Statistics can be Affected by Many Causes

The statistical figures should be affected by a big number of factors. For instance, costs of items
are affected by stock, need, import/export and tallnesses of people are affected by the
tallnesses of their guardians, etc.

Statistics are set in relation to each other

Statistics Collected within a Systematic Manner for a Pre-determined Purpose
In order to make a legitimate comparison the gathered data must be set in relation to each
other (i.e. the data should be homogenous). For instance, the ages of husband and wives at the
time of marriage are comparable and can be placed in relation to each other. Even So, the
height of students their marks in Mathematics have the relationship between them. Hence,
they cannot be equated.
