Forums have six different aggregate types. The aggregate type defines how ratings are combined to form the final grade in the gradebook.

• Average of Ratings*: The mean of all ratings is figured. At least two ratings must be submitted in order for a grade to submit to the grade book.
  
• Sum of Ratings*: All ratings are added together. The total will not exceed the maximum grade for the activity.
  
• Count of Ratings: The number of ratings becomes the final grade. The total will not exceed the maximum grade for the activity.
  
• Maximum Rating: The highest rating becomes the final grade.
  
• Minimum Rating: The lowest rating becomes the final grade.
  
• No Ratings: The activity is not gradable and will not appear in the grade book
