Have you tried =SUM(D4:D24)/COUNT(D4:D24) or =AVERAGE(D4:D24) ?

Hi Tom,

Can you help me with another formula? I am also calculating the averages
of
each particular assignment in the class. How do I omit the blank cells
from
the class average for the assignment?

The formula is:

=SUM(D4:D24)/21

Thanks!!

Suzy

The formula will work equally as well with percentages as with credits so
I
think it should do what you asked.

Good luck with it.
