Question

difference between individual series and discrete series???????????pls tell me fast???

Answer 1

Individual Series :-

In an individual Series, data is in raw form and presented individually. It gives numeric value for a specific situation.
For example - 
Following are the marks secured by the students of a class - 22, 23, 29, 25, 27, 20, 24, 26, 19, 17

Discrete Series :-

On the other hand, in discrete series, data is presented in form of exact measurement and every item takes a definite value. The important thing  about discrete series is that the variables involved in the series have integer value.
For example -
Income                    Number of Persons
  2000                                  7
  2500                                  6  
  3000                                  4
  3500                                  8 
  4000                                  5
  4500                                  3
  5000                                  2
