               SUBTOPIC: Bar Graph

               Bar Graph: The pictorial representations of a grouped data, in the form of vertical or
               horizontal  rectangular  bars,  where  the  lengths  of  the  bars  are  equivalent  to  the
               measure of data, are known as bar graphs or bar charts.

               The types of bar charts are as follows:


                   1.  Vertical bar chart
                   2.  Horizontal bar chart


               To understand the above types of bar graphs, consider the following examples:

               Example 1: In a firm of 400 employees, the percentage of monthly salary saved by
               each employee is given in the following table. Represent it through a bar graph.


               Savings (in percentage)                     Number of Employees(Frequency)



               20                                          105


               30                                          199


               40                                          29

               50                                          73


               Total                                       400




               Solution: The given data can be represented as Vertical Bar Graph.
