P. 4

Suppose we have a row of 30 boys, who like different games-




                     Cricket, Hokey, Football , Chess and Badminton.



                     In such case , we prepare a table containing the available


                     choices.



                     Then , for each boy we mark a vertical line called tally mark


                     against his  particular choice.




                     Once we have a set of four tally mark for a certain choice , then

                     we indicate the fifth mark by crossing the four tally mark . We


                     then start with a new set of tally mark .




                     Suppose the number of boys liking games are as given below :
   1   2   3   4   5
