Depth/independence

Posted by Purple on April 28, 2003

Hi, could anybody help me with the bracketed sentence? I am not quite sure what it means?

Concerns about objectivity's objectivity are no justification for thinking that the SAT is on a par with a random teacher's assessment of a random student's achievement level; (depth does not in general offset independence, and quoting examples where it does is irrelevant to the general claim)

Thanks a lot.
