TABULATION
This section comprises of questions in
which certain data regarding common disciplines as production over a period of a few
years: imports, exports, incomes of employees in a factory, students applying for and qualifying a
certain field of study etc. are given in the form of a table. The candidate is
required to understand the given information and thereafter answer the given
questions on the basis of comparative analysis of the data.
BAR GRAPHS
This section comprises of
questions in which the data collected in a particular discipline are
represented in the form of vertical or horizontal bars drawn by selecting a
particular scale.one of the parameters is plotted on the horizontal
axis and the other on the vertical axis . the candidate is required to
understand the given information and there after answer the given
questions on the basis of data analysis.
PIE-CHARTS
The pie-chart or a pie-graph
is a method of representing a given numerical data in the form of sectors of a
circle.
The sectors of the circle are
constructed in such a way that the area of each sector is proportional to the
corresponding value of the component of the data.
From geometry, we know that
the area of a circle is proportional to the central angle.
So, the central angle of each
sector must be proportional to the corresponding value of the component.
Since the sum of all the
central angle is 360°, we have
Value of the component
Central angle of the
component = ---------------------------------- *
360°
Total value
LINE-GRAPHS
This section comprises of question
in which the data collected in a particular discipline
are represented by specific
points together by straight lines. The points are plotted on a two-dimensional
plane taking one parameter on the horizontal axis and the other on the vertical
axis. The candidate is required to analyse the given information and thereafter
answer the given questions on the basis of the analysis of data.
