Classification
In classification questions, you're given a group of items—such as words, numbers, or objects—and you must identify the one that does not belong to the group. The logic is based on finding a common characteristic shared by most of the options and spotting the one that is different or unrelated.

Types of Classification Reasoning
The various types of classification questions that appear in exams are:
Based on Meaning or Category
Group items sharing a common semantic category (e.g., animals, fruits).
Odd one out does not belong to that category.
Based on Function or Usage
Items are grouped by their purpose or how they are used.
Odd one has a different function.
Based on Numerical or Mathematical Properties
Items grouped by number properties (e.g., prime, even, odd).
Odd one differs in property (e.g., not prime).
Based on Physical Characteristics
Items classified by shape, size, color, or dimension.
Odd one differs in physical trait (e.g., 3D vs. 2D shape).
Based on Alphabetical or Linguistic Features
Grouped by spelling, starting letter, or number of letters.
Odd one breaks the linguistic pattern.
Based on Cultural or Contextual Knowledge
Group items by historical, cultural, or contextual relevance.
Odd one belongs to a different context (e.g., scientist vs. authors).
