Statistics deal with data analysis.
The condensation of data is the first step in rendering
comprehensible a long series of individual observations.
This was made possible by
classifying and tabulating the data and then presenting it in the form of frequency distributions.
Once the frequency distributions are formed, the next step is to study their characteristics, so
that it can be compared with each other.
Frequency distribution may be studied in two ways:
1) By diagrams and graphs
2) By measuring quantitatively.
Study by the first method is less accurate and therefore any conclusion drawn from it may not
be relied upon to a great extent.
So the second method is considered more accurate than the
first one as it involves numbers which can be compared easily i.
e.
which is the greater of any 2 or more given numbers.
Therefore it is necessary that such a
representative number should truly represent the series.
