What is aggregation?

The aggregation dropdown menu lets you choose the aggregation strategy that will be used to calculate each participant's overall grade. There are different options:

  • Mean of grades: The sum of all grades divided by the total number of grades.
  • Weighted mean: Each grade item can be given a weight, which is then used in the arithmetic mean aggregation to influence the importance of each item in the overall mean.
  • Simple weighted mean: The difference from Weighted mean is that weight is calculated as Maximum grade - Minimum grade for each item.
  • Sum of grades: The sum of all grade values.
  • Mean of grades (with extra credits)
  • Median of grades
  • Smallest grade
  • Highest grade
  • Mode of grades
