Sorting data into groups

Eight friends name their favourite game. The answers are in a mixed pile.

Sorting makes the pile easy to read. Each group of answers is a bucket. In the lab, tap an answer to drop it into its bucket. Then find the bucket with the most answers.

Grouping means putting similar answers together. Some books say classification.

Grouping puts each answer in one clear bucket.

Good buckets have a place for every answer. No answer fits two buckets.
