1.2.4 Comparison

Unless figures are compared with others of the same kind they are often devoid of any meaning. For example, if we say that the production of Maruti Udyog Ltd. has increased considerably shall not be meaningful unless some comparison of figures is made. But the statement there has been an increase from 200 cars a day in Sept. 1985 to 1000 cars a day in April 2000 definitely indicates the increasing trend in production.
