### Explanation of Scoring

When viewing the comments for your score, there are 3 groups, each with multiple numbers:

Faculty:

- Score from faculty member(s) for Topics (scale: 1-5)
- Score from faculty member(s) for Aims (scale: 1-5)
- Score from faculty member(s) for Speaking (scale: 1-5)
- Score from faculty member(s) for Timing (scale: 1-5)
- Total score from faculty member(s), i.e. average of above 4 items (scale: 1-5)

Students:

- Number of students that evaluated your presentation
- Score from students for Topics (scale: 1-5)
- Score from students for Aims (scale: 1-5)
- Score from students for Speaking (scale: 1-5)
- Score from students for Timing (scale: 1-5)
- Total score from students, i.e. average of above 4 items (scale: 1-5)

Niceness:

- Number of presentations that you evaluated
- Your niceness in evaluating other students.

For each evaluator, a niceness factor is calculated as a ratio of the average score they gave to the average expected score (3). So if on average an evaluator gave scores of 4, then their niceness is 1.33 (since 4 is 1.33 times larger than the expected average of 3).

The niceness factor is used in normalizing all scores. To determine the score, the actual score given by an evaluator is divided by that evaluators niceness factor. So if an evaluator with niceness of 1.33 give a score of 5 to another student, then that students score would be 3.75.

The final score given for your practice presentation is the average of the total score from faculty and total score from all students.
