An audiologist is concerned about her patients' use of their prescribed hearing aids. She decides to conduct a study. She checks with each of her twenty patients weekly and records the proportion of time per day that each patient is wearing his or her hearing aid and rank-orders each from 1 to 20 based on that proportion. She then provides an educational package of material to each of her patients describing the advantages of hearing aid use. After all patients have received this package she contacts them again and asks about their hearing aid use. She rank-orders the twenty patients this second time in the same way she did the first time. She wants to compare the rankings before and after the special educational material was sent out. What correlation test would you choose to answer the
question? What will be an ideal response?
