A group of nurse practitioners wish to explore the effectiveness of a new treatment approach.

As a member of your agency’s research and practice committee, you review their proposal. They describe how they will use collected demographic data to statistically test the new treatment against the current treatment. They propose to collect the following patient data: gender, ethnicity, religion, diagnosis, age measured in decade categories (i.e., 0–10, 11–20, 21–30, 31–40,), and name of medications currently taken. What feedback can you give to them about their choice of variables and proposed statistical manipulation?
