Statistical Series
1. Individual series : Under this category, every item or values are personally shown differently. Under this category and groups of items and values are not made. Values are presented in accordance to the number of items.
2. Discrete series : When there are more classes in an investigation and their values are confirm then individual value (items) which are different from each other and are complete, are written and their frequencies are written in their front. There are two columns, in one column value of items and other column, frequency of each item is written.
3. Continuous series : When data’s are presented on the basis of class intervals, then this series is called continuous series.
