how to calculate negative agreement and positive agreement

[HitmonTran]

Hi,

I was assigned to calculate Negative & Positive agreement but have no clue where to start.  When I googled, they presented a 2x2 table (true positives, true negatives, false positive, false negative).  however, in my situation I have more than a 2x2 table (see screenshot)

should I calculate them for individual row? (see screenshot)

or should I keep create a 2x2 like the one below?

again, i have no idea where to start, any suggestions will help, thank you.

Perhaps create a 2X2 by making a new variable which combines High Pos and Low Pos into a single Category Positive, and also collapses High Neg and Negative into a single category, Negative.

so you wouldn't separate only High Pos with Negative, Low Pos with Negative, High Neg with Negative? thank you

This is subject matter specific and depends on the question being asked/answered.

You'd need to know the data and how the results are being interpreted to answer this correctly.

No, you want a 2X2.

As Reeza said, how you handle low pos/high neg depends on the subject matter. But the simplest thing for a homework assignment would be to treat low pos as pos and treat high neg as neg.
