Weighting Grades

INFORMATION REGARDING CALCULATION OF END OF YEAR GRADE

Teachers;

As we are entering Q2 grades some teachers have noticed that if you add Q1 and Q2 then divide by 2 it does not necessary equal the Y1 average.  This occurs with classes that have weighted categories, i.e. Tests 50%,
Quizzes 30%, Classwork 15%, Homework 5%.
The reason is this: Q1 categories are calculating all scores for that section of time only. Q2 is doing
the same for its specific dates. However, Y1 is calculating from September to June – so it is averaging all dates during the year.

If you have 30 grades for Q1 and say only have 6 for Q2
since it is not at the halfway point yet, the Y1 is giving more weight to the
quarter with the larger number of assignments. It is averaging 36 grades together, not Q1 then Q2. There are two ways to handle how you wish to view Y1.

First, you can leave everything the way it is. At the end of the school year Y1 will be mathematically very accurate as it will measure the progress for the complete year.

If you wish to calculate Q1+Q2+Q3+Q4 divided by 4 =Y1 because you feel the average amount of assignments in each quarter will not be a fair assessment you may use the following instead for Y1:

Go to Windows>Final Grade Setup. Click on the drop down arrow in the FG
Name field
and choose Y1.

In the Factor Type section, click on the drop down arrow and choose “% from another final grade.” In the Asmt/Cat/FG Name section, click on the drop down arrow and choose “Q1”(this will probably show up by default.) In the Weight section, type in 25. Click on the “+” sign above the Weight section to add the next line. Follow the above directions to add in Q2, Q3, and Q4 to equal 100. Save the changes.

Remember, either choice is acceptable; this is teacher or school preference.
