EOC Q1.19
Dr. Calvin needs just one more participant to complete her experiment. Lisa, a student of Dr. Calvin, has almost completed the experiment when she announces she wants to quit because the experiment is boring. What options does Dr. Calvin have?
a) Dr. Calvin must let Lisa go and find another participant.
b) Dr. Calvin can require that Lisa finish because students don’t have the same rights to quit an experiment as the general public does.
Consider This: There are ethical concerns when dealing with human subjects in an experiment or other type of study. LO 1.10 Identify some of the common ethical guidelines for doing research with people.
c) Dr. Calvin can require that Lisa finish because boredom is not an acceptable excuse for quitting.
