Package	osid.grading.calculation
Description	The Grading Calculation OSID defines a service to apply calculations to `GradebookColumns`. GradebookColumnCalculations A `GradebookColumnCalculation` is an `OsidRule` that is created on a `GradebookColumn` to override a manual `GradeEntry` with a rule. The rule has one or more input `GradebookColumns` on which to calculate a result for the entries in the target GradebookCol;umn. `GradebookColumnCalculations` define several baked-in rules such as averages and standard deviation. More exotic calculations can be done through the attached `GradebookColumnCalculationRecord` or through an associated reusable `Rule`. For example, a `Gradebook` may have one `GradebookColumn` for each quiz of four scores. A fifth `GradebookColumn` can be created to attach a `GradebookColumnCalculation` to average to four input quiz scores. The sixth `GradebookColumn` may contain the input final exam scores and the seventh `GradebookColumn` defined for a custom `GradebookColumnCalculation` that weights the seventh column by 60% and the fifth column by 40% before averaging them. An eighth `GradebookColumn` may be created for an alternate `GradeSystem` (A-F) with an empty `GradebookColumnCalculation` that takes the final score in the seventh column and transforms it to a letter grade for grading submission at the end of the term. Gradebook Cataloging `GradebookColumnCalculations` are indirectly referenceable through the `Gradebook` to which the associated `GradebookColumn` reisdes. `GradebookColumnCalculations` do not have a complete independent service pattern since they are directly attached to a single `GradebookColumn` . Reusable calculations are achieved through reusable `Rules`.

GradebookColumnCalculations

A GradebookColumnCalculation is an OsidRule that is created on a GradebookColumn to override a manual GradeEntry with a rule. The rule has one or more input GradebookColumns on which to calculate a result for the entries in the target GradebookCol;umn.

GradebookColumnCalculations define several baked-in rules such as averages and standard deviation. More exotic calculations can be done through the attached GradebookColumnCalculationRecord or through an associated reusable Rule.

For example, a Gradebook may have one GradebookColumn for each quiz of four scores. A fifth GradebookColumn can be created to attach a GradebookColumnCalculation to average to four input quiz scores. The sixth GradebookColumn may contain the input final exam scores and the seventh GradebookColumn defined for a custom GradebookColumnCalculation that weights the seventh column by 60% and the fifth column by 40% before averaging them. An eighth GradebookColumn may be created for an alternate GradeSystem (A-F) with an empty GradebookColumnCalculation that takes the final score in the seventh column and transforms it to a letter grade for grading submission at the end of the term.

Gradebook Cataloging

GradebookColumnCalculations are indirectly referenceable through the Gradebook to which the associated GradebookColumn reisdes. GradebookColumnCalculations do not have a complete independent service pattern since they are directly attached to a single GradebookColumn . Reusable calculations are achieved through reusable Rules.
