    Let's count similar objects and write in the table given below:

                                    Name of the Item                                   Number of the Item
                       1.  Shuttle Cock                                                            7
                       2.  Football                                                                5

                       3.  Chair                                                                   4
                       4.  Table                                                                   3
                       5.  Hockey Stick                                                            5

                     Now, let's sort the number of items in the above table in descending order. You will get the
                     following data:

                                    Name of the Item                                   Number of the Item
                       1.  Shuttle Cock                                                            7
                       2.  Football                                                                5
                       3.  Hockey Stick                                                            5

                       4.  Chair                                                                   4
                       5.  Table                                                                   3

                        Collect the birth dates of all the students of your class. Arrange the data in descending order and
                        write this data in a tabular form on a chart paper.

                     DECODING

                     Data can also be represented in the form of a hidden/secret message, called as coded data.
                     The hidden message can be in the form of a symbol, number, picture, letter, or a pattern. The

                     process of converting a hidden message to a meaningful text is called decoding. Look at the
                     code below used to solve the sums.

                     Code:

                      A = 1         B = 2        C = 3         D = 4         E = 5         F = 6        G = 7         H = 8

                     Sums:

                     1.   A  × B     =   B       2.   E  × A    =  E       3.   B  × C     =    F      4.   D  × B    =  H

                                                                                                     Data Processing   111
