Types of Classification with Problem Examples

What is Classification? 

‘Classification’ means to assort the items of a given group on the basis of a certain common quality they posses and then spot the stranger or odd one out.

3. Figural Classification

1. Semantic Classification

In such type of question, a group of four words is given, three of them bear a common relationship but one does not bear to the same nature, so form a new group. Candidates are required to select that word as an option which does not belong to a common group.
