- The five numbers of a box plot cut the data into four parts, each holding about a quarter of the scores.
- One quarter of the scores is scores in each part.
- From , the first quartile, up to , the maximum, covers three of the four parts.
- Three parts of about scores each: scores.
- Traps: stops at the third quartile, is only one part, and is a distance, not a count.
