. This graph shows the distribution of skill points, by grade. The Y-Axis shows the self-assessment results. The X-Axis shows the trainer’s assessment. This allows management to analyze assessment tendencies. This graph can be used to help determine if some assessors may be too severe or too easy in their assessments. Also, it is possible to look for unusual data points, such as someone in a grade who is far from others in the same grade, or unusual overlaps of results among different grades.
