the practice or science of collecting and analyzing numerical data in
large quantities, especially for the purpose of inferring proportions in a
whole from those in a representative sample.
Þ
In plural sense, statistics
refers to quantative data, Statistics is the science of counting-Dr.A.L.Bowley
Þ
Statistics is the
collection, presentation, analysis and interpretation of numerical data-Croxton
and Cowden
Þ
“Statistics is a set of procedures and rules…for
reducing large masses of data to manageable proportions and for allowing us to
draw conclusions from those data”
ÞStatisticians are key
contributors to scientific methodologies. They use their quantitative knowledge
to the design data collection schemes, process the data, analyze the data, and
interpret the results. Further, statisticians often make critical evaluations
on the reliability of data and whether inferences drawn from can be made
confidently. They also help to identify misleading abuses of data that may be
portraying an inaccurate account of a situation.
Þ Today, statistics has become an important tool in the
work of many academic disciplines such as medicine, psychology, education,
sociology, engineering and physics, just to name a few. Statistics is also important
in many aspects of society such as business, industry and government. Because
of the increasing use of statistics in so many areas of our lives, it has
become very desirable to understand and practise statistical thinking. This is
important even if you do not use statistical methods directly.
