WC Algorithm (Weights within Categories)

  Previous topic Next topic JavaScript is required for the print function  

 

 

The WC Algorithm (Weights within Categories) also assumes that each task is assigned a relative weight.  As in WO Algorithm,  each Task is assigned a Type Code and each Code is assigned a relative weight.  However, the concept of Categories is now added to the calculation.

 

A Category is a grouping of Task Type Codes that has an assigned percent weight in the Term calculation.  The total of all Category weights is, by definition, 100%.  The term grade is the weighted average of all the Category grades.   Each Category grade is, in turn, a weighted average of all the Tasks having Type Codes included in that Category.

 

Let's simulate the calculation on a simple spreadsheet, with the same Tasks and grades as in the WO Algorithm, but with the addition of Categories.

 

 

First, we have the Task Types and relative weights:

Let's define the Categories as follows, showing the included Task Types for each and the set Term Weights:

Using the same Tasks and grades as in WO, we now perform weighted average calculations for each of the three Categories:

Finally, we weight average the Category grades that have just been calculated:
