Create a dashboard and scheduled reports from a survey results

[velvet]

We are beginning to use surveys.  Each answer on the survey has a number value.  I need a dashboard and report that would show the following and I don't know how to start it, especially the part with the average score of the survey based on groups because assign to of the survey is the person taking the survey, not the Assignmenr group of the Incident that generated the survey.
