Professor Hammond studies ethical behavior and designs a study to examine the amount of cheating at her school. At the beginning of class each day, she passes around a chart showing the dates of the class meetings, with boxes for students to initial if they were present. She photocopies the sheet after each class so she can find if any students initial for days they were absent. She waits for interesting results before writing a proposal for the institutional review board (IRB). Which ethical standard does waiting to propose the study violate?
