You wouldn't be able to say anything with confidence about individuals
without the individual data but this image helps me think about what
individual data would be needed to back up or refute an inference
based on group data.
If you can find data within some groups and they show very little to no
relationship for X and Y then it's a little more likely that you can
use the group inference. But in any case watch out!
