If there is a weighting bucket with no assessment or an assessment without a mark entered, the weight of the empty bucket will not be included when calculating the student’s average mark.
Even though the buckets in the weighting form always add up to 100%, if one of the buckets is empty the weight of that bucket will be evenly distributed among the other weighted assessments until a mark is entered for the empty bucket.
For example, if you have four buckets in your weighting form: quiz, test, homework, and project, all weighted the same at 25% each. All the buckets have marked assessments except for the project bucket. In this case, the other buckets (quiz, test, and homework) will adjust and increase their value (relative to each other) to account for the missing 25% that would have been contributed by the project bucket. Effectively, the other three buckets will actually be contributing 33% to the average. Once a mark for a project has been entered, the weighting will reset – all buckets will contribute their shown average and the 25% value of the project bucket will be applied as well.
