aggregate function across fields?

[Tim Thorp]

I have a scores database where for a given student, they take a number of
tests and their scores for the series of tests are all based on the same
categories. but they are tested across several disciplines. A good example
is that I am testing agility, strength and coordination across tennis,
basketball and volleyball

I designed the database with a field for the sport and one field for
agility, one for strength and one for coordination.

I want to calculate averages and am stuck. It is more easy for me to
calculate the average for agility, but not for tennis.

Is it possible for me to Avg([agility] AND [strength] AND [coordination]) ??

This isn't very normalized. Could you please type in about 10 sample records
as well as the expected results/display?

Thanks for writing!!

10 records where Station ID is what is being tested follow here and a good
example of the output is for examID 1341, I want an expression that will
yield the average of the values stored in Moral1, Moral2, Moral3, Moral4,
Moral5 :

The average of the Moralx fields I believe should be:
=IIf( (5 + IsNull(Moral1) + + IsNull(Moral2) + IsNull(Moral3) +
IsNull(Moral4) + IsNull(Moral5) )=0, 0, ( Nz(Moral1,0) + Nz(Moral2,0) +
Nz(Moral3,0) + Nz(Moral4,0) + Nz(Moral5,0) ) / (5 + IsNull(Moral1) + +
IsNull(Moral2) + IsNull(Moral3) + IsNull(Moral4) + IsNull(Moral5) ) )

If your data was normalized this would not be such a horrible expression.
