Quizplus · Accepted Answer

Experimental mortality refers to the loss of participants during the course of the study, and in this example, some students left the program due to a conflict with sports, which could impact the internal validity of the study by creating bias in the remaining participant sample. None of the other options (instrumentation, selection-maturation interaction, statistical regression, diffusion) are directly related to the loss of participants.
