Abstract
Games and sports are the source of enjoyment, amusement and pleasure. No
other living being but man needs games and sports for his mental recreation.
All other living beings need only the ways and means of living and surviving,
because they strive for food and satisfy hunger. Men are the rational beings
and they need to develop their faculties to expose themselves in various fields.
So, they require the soundness of body and mind for which games ,sports and
healthy food are necessary.
Over the past decade terms such as ‘data handling’, ‘exploratory data
analysis’ and ‘data visualization’ have replaced the use of the term ‘statistics’
in the secondary curriculum. The current meaning of data handling emphasizes
collecting, organizing, representing, analyzing and interpreting data closely
connected to the world of the pupils. The visual representation of data is of
major importance at the secondary level. Data handling is seen as going
beyond statistics (the science of data collection, representation, analysis and
interpretation for decision making). Statistics can be said to be the content,
data handling is the whole learning environment in which data are explored.
A double bar graph is used to comparison.
