Let's look at graphing a set of SAT exam scores by a group of students.
Students from one school took the SAT. This is Group 1. The information about this data is shown in the following table. Use this to make a box plot and write a description of the data set.
| Measure of Central Tendency | Value |
| Minimum Score | 1600 |
| Quartile 1 | 1700 |
| Median | 1820 |
| Quartile 3 | 1920 |
| Maximum Score | 1950 |
| Mean | 1780 |
| Interquartile Range | 220 |
| Standard Deviation | 155 |
The lower quarter of the students scored in the 1600 to 1700 range. The middle 50% scored between 1700 and 1920, a 220 point spread. The top quarter of the students scored between 1920 and 1950. The standard deviation was 155.
