results/result

WB I sorta disagree with Tes. Choice depends upon whether or not and how you consider these results as a unit

What do you disagree with?

Um...do you mean in American English, 'that' could be used in the situation I mentioned in the first post?

-Results of the XYZ exam of our school compared to that of all schools can be found online.

Si WB

Nope.

Original question:
Results (plural) of Okinawa School students (plural) compared to those (plural) of Japanese Candidates (plural) in the AL exam have (plural) been released.

Modified question:
Results (plural) of the XYZ exam of our school compared to those (plural) of all schools (plural) can be found online.

You wouldn't say "The hats of all the boys were bigger than that of all the girls", at least I hope you wouldn't.

Yes, sorry.

No Tes but results we'd think of as being combined by some means into a unit, then compared to another unit calculated by the same means

Then the sentence would say so, but it doesn't.

Good answer. Thank you.

Tes it's implied

Help, somebody

Results (plural) of Okinawa School students (plural) compared to that (singular) of Japanese Candidates (plural) in the AL exam have (plural) been released.

The 'implications' are all the other way. The singular 'that' sticks out like a sore thumb.

Maybe you were thinking of something like this:

The average result of Okinawa school students compared to that of Japanese candidates has been released.

Oh no, here I am confused again:

When do we use average result/results?

When discussing an average result.

No no, I mean, what's the difference between the singular and plural?
