In the previous class, we have learnt how to apply the concepts through visualisation. In
                  this class, we are going to learn how to interpret the data and process the information.

                  Data and Information

                  Data refers to the raw input. When this data is processed, the outcome received is known
                  as information.

                  Look at the given table of students with their marks obtained in the exam.

                  This tabular format represents the data, which gives us the information in a neat and clean
                  manner. It becomes easier to read the data when it is presented in such a format.

                  Representing Information


                  Let us study about some of the ways in which we can represent information.
