Dr. Schmidlap is coming near the end of a four-year-long study in which she followed college students throughout their careers. It has been a struggle because her department did not have enough funds for her to adequately compensate her participants.
When she started, she had 75 student participants. Whether it was due to the fact that she was too nice or that she did not adequately enforce the signed agreements, many students stopped participating and returning her emails. Now, nearly four years later, she only has 35 participants left. She is a bit worried and would like to come up with a strategy should more students discontinue the study.
What would be an ethical and effective way for her to proceed?
