Answer: Statistics
plays an important role in almost every facet of human life. In business
context, managers are required to justify decisions on the basis of data. They
need statistical models to support these decisions. Statistical skills enable
managers to collect, analyse and interpret data in order to take suitable
decisions.
Statistics is used for various
purposes. It is used to simplify mass data and to make comparisons easier. It
is also used to bring out trends and tendencies in the data, and the hidden
relations between variables. All these help in easy decision making. Let us
look at each function of Statistics in detail.
1.
Statistics
simplifies mass data: The
use of statistical concepts helps in simplification of
complex data. Using statistical concepts, the managers can make decisions more easily. The statistical methods help in reducing the complexity of the data and in the understanding of any huge mass of data.

Statistics
makes comparison easier: Without
using statistical methods and concepts, collection of data and comparison would
be difficult. Statistics helps us to compare data collected from various
sources. Grand totals, measures of central tendency and measures of dispersion,
graphs and diagrams and coefficient of correlation all provide ample scopes for
comparison.
3.
Statistics
brings out trends and tendencies in the data: After data is collected, it is easy to
analyse the trend and tendencies in the data by using the various concepts of
Statistics.
4.
Statistics
brings out the hidden relations between variables: Statistical analysis helps in drawing
inferences on the data. Statistical analysis brings out the hidden relations
between variables.
5.
Decision
making power becomes easier: With
the proper application of Statistics and statistical software packages on the
collected data, managers can take effective decisions, which can increase the
