              Data

              The information collected in the form of numerical figures is called data. By presenting
              it in an organised way, meaningful information can be gathered from it.


              Organising Data

              Data can  be organised  in a table  using  tally  marks which  is a quick  way of  keeping
              track of numbers or observations in groups of five.

              We use  vertical  line(s)  (|)  to represent  tally  marks.  We draw one vertical  line  (|)
              for every observation (number).  Upto  four observations  we draw four vertical lines
              and the fifth observation is represented by a line runs diagonally over the previous
              vertical four lines.

               Observations                  1             2            3            4            5            6
               Tally marks                    |           ||           |||         ||||                           |

              Look at the following table. It represents class IV students who like different fruits.

                         Fruits name                       Tally marks                   Number of students

              the  zoo, the  children were asked about  their  favourite animal  and  their  responses
              were noted down as given here:


                  Lion         Tiger      Elephant     Monkey         Bear       Monkey         Zebra      Elephant
