Difference Between a Collection and a Set
What is the difference between a collection and a set? Give reasons to support your answer.
Solution
| Collection | Set |
|---|---|
| A collection is simply a group of objects. | A set is a well-defined collection of distinct objects. |
| A collection may or may not be well-defined. | Every set must be well-defined. |
| Example: “Collection of good teachers” is not clearly defined. | Example: \[ \{a,e,i,o,u\} \] is a set of vowels in English alphabet. |
Hence, every set is a collection, but every collection is not necessarily a set.
