Question 35

[Guest]

#35 has no explanation for why the answer is D rather than A.

The passage could be summarized by the following statement: The limitations of statistical criteria in hospital classifications. Over and over, the author sticks to that theme. Answer choice A suggests that it would be easy to measure empirically and convert into mathematical (ie statistical) variables which runs counter to the author's repeated suggestions.

Answer choice D ("There is little need to include additional measurements in multiple cross-classification.") is actually consistent with the passage. In P4, the author states that adding additional measurements would have a negative consequence: "Finally, adding additional measurements will drastically increase the number of associated classification cells and the number of clusters, thus reducing the possible number of hospitals in each cluster."

Since the purpose of the article is to show that 'current techniques are inadequate', any NEW statistical technique that would lead to a different outcome would strengthen his argument.
