PPT-FREQUENCY DISTRIBUTION AND GRAPHICAL PRESENTATION OF DATA

BY Manisha Kadam The arrangement of data in different groups on the basis of some similarities is known as classification According to Tuttle A classification is a scheme for breaking a category into a set of parts called classes according to some precisely defined differing characteristics possessed by all the elements of the category.
