Classification (Odd One Out)
Classification questions give a small group of items where three (or more) share a clear, definable property, and one does not. The skill is identifying exactly what property connects the majority before deciding which one breaks it.
Common patterns
- Category membership (fruit vs. vegetable, city vs. country)
- A shared numeric property (all prime, all divisible by a number)
- Physical or functional grouping (2D shapes vs. a 3D solid)
Worked example
Question: Apple, Banana, Carrot, Mango — which does not belong?
Answer: Carrot
Apple, Banana and Mango are fruits; Carrot is a vegetable.
