Question : Formula Help - Excel 2007

Hello Experts,

I have Five cells on my worksheet that contain values that I use for a Evaluation from 1 - 5 (5 is the highest)
I start with a formula like =(H2+K2+N2+Q2+T2)

My problem is some of my coworkers will not attend the class so they will not vote.

Because they did NOT vote the formula =(H2+K2+N2+Q2+T2) may produce a score that is NOT a true repesentation of how the class was evaluated by the individuals that were in attendance.

I am wondering if anyone has an idea and a formula that could help me get accurate scoring system.

Regards,
Chris

One approach is to multiply by a weighting factor:
=SUM(H2,K2,N2,Q2,T2)*5/COUNT(H2,K2,N2,Q2,T2)

If only 4 people respond, then you multiply the score by 5/4
If only 3 people respond, you multiply the score by 5/3

The net result is a weighted score that has the same magnitude as if all five people voted.
