Classification is defined as the method of sorting the various items of a given group based on certain common qualities they possess and identifying the odd one out. The classification section addresses different categorization standards that can be applied to group the items. This classification may be based on some common characteristics they have, such as shape, number of sides, division of figures, etc. So, the things that have these qualities in common are grouped, and the object that doesn’t—the odd one—should be taken out of the group.
