Answer 1

Here are the statistical measures for the given set of data:

Mean: 6.5
Median: 5
Mode: 4, 9
Range: 10
Variance: 9.75
Standard Deviation: 3.12

Below is the box and whisker plot for the given set of data:

3
|
------4---4---4------
|
------5---5----------
|
------7--------------
|
------8--------------
|
------9---9----------
13

Key:
- Lower whisker: 3
- Lower quartile (Q1): 4
- Median (Q2): 5
- Upper quartile (Q3): 9
- Upper whisker: 13
