Calculating Averages

Hobbes,

I suppose you could also do a weighted mark-up if called upon to do so

That would only be- logical

TC was right then?

thanks for the info then, chaps

It depends.

If each test has equal importance (regardless of the number of questions) then Skweeky's method is correct.
If each question has equal importance then TCLite's method is correct.

Theoretically, Hobbes' method would take both into account, but since we don't know the relative importance of each test it is not helpful.

Yes

Lynx is a muppet.

If you totally disregard the "missed" test, you are up around the 77%

24/25, 17/20, 14/20, 0/40 and 18/30

But Lynx, we do know the relative importance. Don't we?

[lynx]

No, all we know is the relative number of questions.
For example, in the test with 40 questions they might all be 2 + 2 = ? type questions, so each question would not be very important at all.

The amount of time allowed for each test is usually an indication of how hard the test is (compared to others), and could be used as a relative weighting for the test.

If all the tests are allowed the same amount of time it would indicate that a test based average is called for so you should use Skweeky's method.

[J'Pol]

So one answers the question based on the data supplied and does not assume extra criteria.

My reading of the question was what was my overall percentage. If however this is not the case then 3 can let us know what it is he really needs to know.

[Skweeky]

yes, that was what I was thinking to. Here it usually doesn't matter on how many points the test is, they all have the same weight

Not really surprising given the socio-economic and cultural diversity.
