              PicTograPh

              When we make use of pictures or symbols to represent information, we call it pictorial

              representation or pictograph of the given information.
              A pictograph helps us to compare information.

              Every pictograph must have the following:
                  •  title: The title tells us what information the pictograph gives.
                  •  Key: The key tells us the meaning and the value of the picture or symbol.

              Drawing a Pictograph


              Ritu's mother records the data regarding the number of milk-bottles sold by a milk-booth
              in a particular week. Ritu wants to represent it using a pictograph.

               days                              Monday     Tuesday     Wednesday Thursday Friday           Saturday

               Number of milk- bottles sold          40         60          80           50         30          70
              To represent the data pictorially, she choose a milk-bottle as a symbol. She assumes the

              symbol of one milk-bottle   represent 10 milk-bottles.

              We shall draw (40 ÷ 10) = 4 bottles for selling on Monday, (60 ÷ 10) = 6 bottles on Tuesday,
              (80 ÷ 10) = 8 bottles on Wednesday and so on.

              Thus, we have the following pictograph.

                                    Number of milk-bottles sold by a milk-booth in a week



                Monday



                Tuesday



                Wednesday
