The best way to study is to attempt to do these problems on your own before looking at the answers.
These problems are continuations of the problems in the summarizing data exercise set. For each problem, find the five-number summary and the mean and standard deviation.
The data below lists the number of times the students in a class were absent.
0, 2, 0, 1, 0, 0, 2, 0, 0, 0, 0, 2, 4, 4, 5, 1, 0, 2, 0, 0, 2, 2, 0
The data below lists the grades of the students in a class. Each grade is associated with a corresponding number of grade points as follows:
| Grade | Points |
| A | 4 |
| B | 3 |
| C | 2 |
| D | 1 |
| F | 0 |
Find the descriptive statistics based on the distribution of grade points.
F, A, C, B, B, A, B, B, A, A, A, C, A, B, C, D, B, A, A, C, D, C, A, C

A simple random sample of camshafts at an automotive engine plant was collected and the lengths of the camshafts measured. The resulting lengths (in millimeters) are given below.
600.8, 599.4, 599.4, 599.8, 599.4, 598.4, 599.0, 599.0, 598.6, 599.8, 599.6, 599.2, 600.6, 599.2, 600.4, 600.4, 601.2, 599.4, 600.0, 599.8, 599.8, 599.6, 600.2
