| 5548090476 | Five Number Summary | Smallest observation, first Quartile, median, third quartile, largest observation, written from smallest to largest | 37 | |
| 5548090477 | How to make a box plot | A central box is drawn from the first Quartile to the third quartile A line in the box marks the median Lines (called whiskers) extend from the box out to the smallest and largest observations that are not outliers Outliers are marked with a special symbol such as an asterisk | 38 | |
