There Are Very Few Studies That Use Data Aimed at Disentangling

There are very few studies that use data aimed at disentangling the relationship between quality of care and litigation activity against nursing homes. Lobbying groups have funded most national studies on this issue. Researchers began by looking at the nursing home information stored in Westlaw's Adverse Filings, a lawsuits database. This database would most likely contain:

A) qualitative information.
B) primary data.
C) projective data.
D) advertising information.
E) secondary data.
