So I did my homework and feel not even 10% sure of myself.

I usually suck with wordy problems. Did I answer this right and if not, can I get an explanation? The whole page in general would be nice to know.
I have a learning comprehension and I've tried contacting my instructor for office hours and we can't make schedules work.
Here is a screenshot of my homework. I am generally looking for advice on #9 and if I tackled 6-8 wrong, please let me know too.

I'm probably way off on some of this. I'll probably be better with the actual numbers. I really want to understand this though but in some cases, it's not sticking.

I've always had trouble figuring out whether something is interval or ratio. Very frustrating.

Well, how do you judge the measurements you know? Just curious of your method of knowing.

I could pull out my stat class notes but uh lets see what I recall...

For #6 the DV would be recidivism rate. They are looking for a specific relationship but the DV itself is the generalized effect in a relationship/study, not a specific one. And the unit of analysis should probably be more specifically people who have been arrested.

For #7 the IV should be the architectural design of the prison and DV just inmate-on-inmate assaults.

#8 looks fine.

Nominal - the number is only a name or title. It has no relation to the other numbers.
Ordinal - rank order like 1-5 scale
Interval - similar to ordinal but the distance matters because it is not an arbitrary scale such as temperature
Ratio - like interval but there is a clear 0 that means there is none of the variable

Income is ratio
I think victimization might be nominal...

I may be wrong on all of this D:
